The IOTAVX SA3 Integrated Amplifier! Badass Affordable-Fi.

[@SHAVEFAN71]

I bought the SA3, but ended up getting the Emotiva Basx A2 amp. I wanted the power of the Emotiva and the flexibility from SA3. Also bought the NP3 from Iota. Paired these up with the Triangle BR03 speakers and Fluance RT85 and U-Turn tables. Makes for a killer set up in my room. I get lost and spend hours in there listing to my records. Keep up these vids, you're killing it!

[@michaelmityok1001]

Another A+ review. Example why? The bonus section contrasting this amp with the NAD is so useful as a buying guide that every other reviewer on youtube could learn from it. This is what audio equipment reviews should do imho, and short of providing detailed measurements too, this is as good as it gets folks.

[@ZeroFidelity]

Thanks for the support, Michael. Drawing up direct comparisons isn't always possible, particularly in a video format where people *demand* to see what I'm talking about. I'm lucky to have the NAD still hanging around so I could feature it in the vid.

Sean, as an update on this IOTA SA3 Integrated Amp, now owned for 11 months. As soon as I received it and plugged in the speakers , it was noticed that 2 of the speaker connections were "loose". I called IOTA, Tech Support walked me through opening the "hood" which I rerally don't familiarity with, found that the fittings on 2 speaker connections were loose. I tighened them very carefully and was good from there. Now, this week, while playing Streamed music via BT, I noticed a scratchy sound. Thought it was bad BT signal, so I played the same signal on another system - no such problem. Switched the speakers to see if it was the speaker (the problem was prominant on the Left Channel, but heard on bother channels). Not the speakers and agter switching the speakers , the entire left channel was out. I shut the unit off. Restarted it 1 hour later, the sound returned played clearly for a short while and then got scratchy again. Now the left channel is out & done. I emailed IOTA , and waiting to see what they advise. I will tell you, this doesn't bode well for this SA3 cause sad disappointment.

[@gprider1525]

Did you ever get this issue resolved? I ask because I'm having low volume issues with the bt module & awaiting a response from iota

I think your doing a great job bringing more people into this crazy ass hobby.

[@anthonyseaford680]

I live in Lancashire, UK, less than 100 miles from Iota Enterprises, but had never heard of them until I read your rave review earlier this month. After some enquiries, I decided to purchase their SA3 Integrated amp and am delighted with the sound quality from such a modest piece of equipment. But it gets better. Today, I checked out the Tone Control and was surprised and pleased at how well it works to correct Room Acoustic problems, and it is so easy to use. In fact, it works as well as my TacT Room Correction preamp that cost some 3 to 4000 GB Pounds! To have this capability in a £399 Integrated amp is absolutely amazing. As a consequence, I am contemplating the purchase of the optional PA3 power amp to get a further improvement in sound quality. IOTA Enterprises deserves every success with products like this. Well done to them.

[@paulwibb.8944]

Hi, can you buy direct from them, not looked them up yet, just saw the review and am very interested,, Did you demo the units,, ??

[@Core-Truth]

Hi Sean, I Just purchased the SA3, PA3 Stack, and the Bluetooth dongle based on your (and others - to a lesser degree) recommendation. I think it's a great value and a good place to start as I begin my audiophile journey. I also subscribed to your channel. I wholeheartedly agree with your honest and practical approach to audio. There's room for everyone in this hobby and audiophiles that look down their noses on other's choices and opinions take the joy and excitement out of any learning experience. Keep up the good work and thank you for the hard work you do. - That's right people running a channel ain't easy.

[@roquesoprano913]

I have the stack too and looking for upgrade my good but entry Elac b6.2 speaks. what speaks are you listen to?

[@martybousum1010]

I pulled the trigger on the SA3/PA3 combo and have never looked back. One of the smartest decisions I have ever made in my pursuit of great sound at prices I can afford. I did the SA3 first, then after deciding on some new speakers (87DB @8ohms, close out special from GR Research) I snagged the PA3. Speaker cables from Blue Jean Cables, and the Audiolab 6000CDT. The SA3 has a great DAC which saves on some money, AND contributes to great audio. I also recommend the Bluetooth Dongle. It opens up music/movies on the internet. Ian, at IOTA is a straight up solid dude who cares about his customers. My units arrived in 3 days from the UK, packaged more adequately than necessary, which shows great care. I have reached the end of my pursuit. I listen for hours every day!

[@iamsabit1337]

That is such a beautiful design. Very simplistic yet elegant. Love the led ring around the gain knob!

[@paulsweeney70]

I just wanted to say, I've been watching your videos for a while now and I've learned so much about audio gear and the industry in that time. I like how you talk about sound and the pleasure of it rather than just pure measurements.I bought the SA3 on the strength of your 3 reviews (and a few other KZbinrs too!). I have to say I'm stunned by how good it is. Your assessment of it is bang on the money. I was going to play it safe with an Onkyo/Marantz/Cambridge, but I'm glad I didn't and I went for something left field like the SA3. Thank you so much - please keep on doing what you do. Now, if I can only sneak it past the wife, I'll add the PA3. Cheers Sean!

@@IamVintage72 I really enjoy this unit. The sound clarity and reproduction sounds way better than my AV receiver. It is hard to put it into words really, but the experience was worth every penny. I use the UB 52 as my front channels, powered by the SA3. My other UB52 center channel and UB51 surrounds are running on my AV receiver. I purchased the PA3 unit late January and it still hasn't shipped from IOTAVX. I question the stability and organization of this company, nothing should take 3 weeks to prepare for shipment, even internationally. But yes, short answer, I would buy it again.

[@davidperkins4139]

Zero Fidelity just my opinion: I think a lot of people are searching more and more for the diamonds in the lesser known audio world that have real value. E.G. tekton, Buchardt, dayens?, etc. As you well know, the markup on mainstream hifi is startling, so buying equipment from smaller, maybe newer, companies is attractive. If tekton decided to start selling in retailers, the double impacts would cost over double what they do now. They’d still be good for that price, but people wouldn’t marvel over them like they currently do.

Hey Sean, enjoying this with my BR03 so much! Thanks again. A quick experiment for you. As the IOTAVX does not have USB I stream Amazon Music HD from my phone or Mac through the Bluetooth which actually is 24 bit aptx. I have to admit sounds fantastic.

Might be intersting to compare sound quality between Bluetooth and connecting the laptop or phone to a cheap DAC as source to the IOTAVX

Hey Guy. You and me both :) S400's are badass speakers. They scale up pretty well with up-level equipment, so matching them to the right amp under $1000 USD can be a challenge.

They have a 7.1 pre-amp/processor to match that 7 channel amp, too. Might be worth just considering a total system replacement and letting someone else take over the Pioneer.

[@Chiroman527]

Sean, Another update and observation after some tinkering. My IOTA SA3 is connected running in unison with the PA3 AMP which is also connected with the PA3's preout to a Emotiva A300 Amp. My Denon DRA-800H Receiver has a Zone 2 Preout connection. That is connected to the SA3 , which allows me control of the Zone 2 Volume and also allows me to Adjust Bass / Treble controls to the speakers connected to this part of my system. What I learned yesterday with some experimentation, was the ZONE 2 master volume on the Denon was set too high !! It appraently was feeding too much power to the SA3. When I lowered the Master volume in the Denon's setup menu to a lesser level, the speakers connected to the PA3 Amp were clear , and not Raspy / Fuzzy as I posted yesterday. However, the Left Channel on gthe SA3 (the Integrated Amp), is not functioning. I had not realized that I had the ZONE 2 master volume - and thus the output set at the maximum level which I may have altered last week or so and set it the Max. When I connected the Denon's ZONE 2 preout directly into the Emotiva A300 amp inputs, with the ZONE 2 Volume preset at the MAX (98) it nearly Blew the Roof off the house. That direct connection to the Emotiva does NOT allow for Volume controls on the AMP - there are none. A Miracle that didn't Blow up the Speakers. I then reset the ZONE 2 volume down and reconnected as described above, the fuzziness in the speakers was gone... Too Much Power . I post this as an experience in Stereo !!

"Dude whats the deal?" he said... "I've tried every amp of the same price and many costing 4-5 times more and the Iota outperforms everything I've put in front of it and by a big margin. The bottom line is I'm keeping it in my studio and it's now my new go to reference I use to compare the competition.

@@Devilsplaylist so far so good for me, drives them to pretty insane volumes in my fairly small apartment. I have found that the ultras tend to chuff a little bit at some higher volumes with tracks that have tons of low end. But, I splurged and pulled in a sub from svs and haven't had any issues so far. They sound incredible, image really really well and can fill a small room at -30ish db on the amp. The sound signature is fairly u shaped since both the ultras and this amp have the sameish sound signature, like what zero fidelity points out in his videos. So if that's what you're looking for, go for it! I've been incredibly impressed.

I know this comment sounds pretty harsh, but I want to make sure you know what you're going to get. I love them and plan on holding onto them for a long time.

Thanks for all the hard work you put into your videos. I have a question that I think you can help me with on whether I should consider "upgrading" to the iota. I'm mostly a vinyl and cd listener. I run a Schiit Saga pre into my NAD C370 and use it with the tube buffer and vintage tube. With this combo my NAD is now sweet and spacious, sounding more high-end. My speakers are 87db Philharmonitors (older version) which love power, so this is a great match. Since you have experience with the C370, will a change to the iota be worthy or should I stay put?

[@Justwantahover]

@@donde2k Thanks, I gave up on any amp except maybe a MOSFET (which are expensive like tube amps are). My amp is supposed to be a "MOSFET" but the data I actually heard on it is vague to say the least. And the amp only cost $300 (new) and if it was like most MOSFETS you could easily add a zero to the price. Nevertheless it's a very good amp and it literally KILLS my NAD (that cost 3 times the price). So after doing that (surprising) comparison I will only get a MOSFET. It's a design difference. I think the transistors work differently and so sound different. They say MOSFETs sound more "tube like" than most transistor amps. I did a comparison of both amps with speakers (that had tweeters with no metal diaphragm). And my cheap "MOSFET" amp makes the cymbals sound more "metal" like than the NAD does...just to give you an idea of what I'm talking about.

Happy New Year 2021 Sean, Do you think this Iota Integrated Amp would serve well as the Zone 2 Amp running off the Denon DRA-800H Receiver . The Denon has 2 Preouts to connect to a separate Amp to drive a pair of Bookshelf Speakers in a different room (I will be using my currently owned Fluance Signature Series HiFi Bookshelf speakers ). BTW, I should have done more Homework during 2020. I probably purchased the wrong Receiver for my Primary purpose - to play 2.1 Channel Stereo music in my Basement Studio / Mancave / Home office created during the COVID Hibernation. I'm a Music lover , 69 yo, and in my haste to create this "basement studio", I purchased a new Receiver (tried a Pioneer and a Yamaha and returned both), settled on the Denon even though I do not have video /surround sound added (yet?) , purchased various Bookshelf speakers ( Polks, Sonys , Fluances, and finally Elac Debut 6.2s - sent the Sonys and Polks back - kept the Fluances ), a nw AT-LP120XBT TT and 2 Tascam units (CD-RW900mkII and a Dual Cassette Recorder player. Just got a Pair of the Elac Debut Reference Speakers (now paired with the Elac Debuts in a A and B speaker configuration). I had the Flus paired with the Elac Debuts , and they played very well together in the basement studio [finished basement of about 400 s. ft]. - yes, I know a No-No in audiophile land of mixing speaker brands ..... The new Elac Debut Reference speakers are Outstanding and pair very well together. I play my drum kit in the basement too. Now retired (Oct 2020), after working from home since March. The Flus at $200 fpr Bookshelf speakers are very good. I decided to keep them and now will put them to another rooms use with the aforementioned request for your opinion for Zone 2.... or use them in a future Surround Sound complete Video setup in the "mancave"[Sorry, I hate that term, but it does serve a descriptive purpose now].

Those other guys come off sounding like shills because even if the piece has caveats that heavily outweigh the pluses, they will give a rave review to the highest bidder, be it for ad dollars or favors! It's like watching the home shopping network paid ads with those guys (90% bull shit, 10% real content). Affordable Hi-fi is not that rare, but affordable "Badass Hi-Fi" is rare and does indeed deserve the word!

@@ericelliott227 As always man, I appreciate your recognition and kind words. For me, a rave review isn't a pay day. Instead, it's the opposite: It's like putting my neck on the proverbial chopping block. All I can do is hope that the folks who spend their hard earned cash experience the same thing that I did.

[@ericelliott227]

@@ZeroFidelity Exactly, that is what needs to be considered and recognized for any journalist/reviewer, whatever. I never did "rave reviews". While I was not out to be a full-time reviewer, taking stuff in from manufactures and such like you and Ron and others do, I was like you, "just the facts Maam" for what pieces I did review. I'd occasionally say whether or not I personally liked something, but always caveated it clearly stating it was my sole opinion. Amp makers seek neutrality in making their amps, I was seeking it in my writing. Even though I was not super popular and such, I still turned down many a request from manufactures, etc. Just not really working that side of the street. I do "how-to" stuff though, such as care and maintenance, so just doing that one is sticking their neck in the guillotine. Get it wrong and lots of trouble comes your way.

Paul Wibb it’s even better than it was, after many hours use this one is a keeper. Just got a crazy deal on a Rotel CD14 for $250 and using the CD14 internal DAC into the Iota it’s crazy good, even my wife mentioned how good it sounds and she has no interest in audio gear.

After watching the reviews I instantly ordered the Iotavx sa3 for my Monitor Audio Studios and I cant agree on the review more. I don’t think you can get a more neutral sound for that money out of a lot od stereo receivers. And for my studios it has easily enough power... no need for a pa3 at all. Crisp clear bass, not too much just the right amount. Love it and won’t exchange it back with my marantz.

Yep, the Outlaw receiver ( $ 850. ?) is pretty much unknown I suspect - it'd probably be my first choice, ' classic' styling that I like, reasonable but getting expensive price. I'm strongly with the style / perf. of early - mid '70's gear given a 6x inflation rate makes a Pioneer 636 receiver an absurd $1800. or so.

Hi Shawn, I have followed several of your videos, especially about amplifiers. I am searching for a match to my Nubert speakers,. I found either the IOTAVX or the XYZ edge interesting. First question: which one would you give priority? Second question: would the saga preamp be a good partner for the XYC? Third question: what solution as a streamer? My music is very diverse, rock, jazz, classical, therefore I was searching a neutral chain. Regards from Germany

ps - not to drag this out , a third bit I dislike - apparently all the controls are on the remote. baaaaad idea if true. I've never had a remote last more than 5 years and I'd expect a stereo to last double that, +. not to mention simply getting lost. chances of a replacement original remote being avail in 5 years ?

[@HowieHaigh]

@@rickc661 I've lived with my SA3 for a few days now and one push on the control knob puts you into source selection mode; a long push puts you into bass/treble/balance adjustment mode. It's taken maybe 24 hours of use to get the amp to open up and show its true ability and I'm now happily impressed. Oh and BTW I've never had a remote fail on me (oldest kit I'm running is my Sony MXD-D3).

I got the pa 3 to go with my denon 3600h. it is a wonderful combination.

[@Chiroman527]

Sean, my previous comments pertained using the SA3 as a secondary Zone 2 Amp to my Denon DRA 800H Receiver. I got one yesterday. I hooked it up to a Teac CD / Cassette player directly just to test it.. tested that setup with 2 bookshelf speakers: a pair of Fluance Signature Series Surround HiFi Bookshelf speakers and new Elac Debut Reference speakers. This was tested vs the Denon DRA 800H Receiver. Honest assessment, I would say , the Iota was a bit inferior. Now to be fully transparent, I used the Denon with Tascam CD player recorder which has Digital optical connection. The Teac was connected via RCA connections. That probably made a difference too I'm sure. FYI, the digital optical connection on the Tascam to the Denon , playing audio CDs is absoultely fabulous... a quick question. Would i be able to connect the SA3 to 1 pair of the speakers which is also connected to the Denon? Of course, not to be played simultaneously.

[@PeterMilanovski]

Looks like they have taken the minimalist approach... While that sort of thing appeals to some people, I prefer knobs and switches. And instead of the backlit branding, that spot would have been better used for a level meter... But then again I'm old school when it comes to amplification and I still believe that amplifiers were perfected some time ago and manufacturers have been going backwards since...

[@ZeroFidelity]

Oh yeah. The SA3 (by its lonesome) outputs 45wpc into 8 ohms and 90wpc into 4 ohms.

Doubles down, nice. Little wonder that it can play with your stable of speakers.

Make sure you tell Sean Casey at ZU that Jeff Adams says hi. The red, white and blue ZU room guy. He’ll know who I am. :) But I have been SERIOUSLY looking at a nice integrated class a/b amp that can put out some power and that had a Wolfson DAC. I just ordered a pair of Magnepan LRS’s. So this might be a really good match.

[@jeffadams9699]

Zero Fidelity Oh and when you mentioned Nakamichi, it brought a big smile to my face. I used to own a bunch of Nakamichi gear in both the home and car audio world. In fact one of my last serious car audio competition systems, the head unit was a Nakamichi. So I have no doubt that IOTA is of good quality.

[@khg7339]

Hi everyone, may I ask for advice? My 42 year old yamaha cr400 needs a replacement, but I’ve only had the chance to compare it to an old NAD3020, which is too warm for me and the stereo amp part of a recently purchased Marantz a/v receiver, which I feel makes everything sound too beautiful and too similar, for instance it takes the rough edges and natural white noises out the saxophones, making them sound like a different instrument. The Yamaha, on the other hand, lacks the beautiful low end of the Marantz, and may seem a little rough on the upper mids at times, but every instrument and voice seem so real, the timbre and tone are really accurate I guess what I’m looking for is a natural sounding amp with a little more of the entertainment factor lacking in Yamaha, but I can’t spend much, unfortunately, so I’ve narrowed it down to: Yamaha as501 (I like how the old one renders instruments and voices; Marantz pm6006 (too sweet but fits the aesthetics of av and cd player) Onkyo 9130 (has pre in-outs for av receiver). Do you feel this could be a worthy addition to the list?? I already have it on the shopping cart and it’s 3:44 am, am I at risk of taking a terrible compulsive decision? hehe Many thanks for the wonderful review, cheers!!

[@ZeroFidelity]

It's impossible for anyone to say what will make you happy. At least not with a 100% degree of certainty. The best I can say is that the SA3 should be able to do what you're looking for. The only thing you'd risk is return-shipping costs, which I admit may be heavy depending on where you are. It's not overly warm, or too old, or too homogenizing.

[@khg7339]

Hey, many thanks for answering!! It’s so hard to choose when there’s no chance to audition components which will presumably accompany you for a long time... I think I’ve narrowed it down to the A s701 or this...the power amp is tempting too...

[@oldskool80sfan12]

​@@khg7339 If the Yamaha lacks the low end get yourself a subwoofer, My Pio lacked the low-end got myself a used MK subwoofer now it sounds like a Marantz with better details :D now I’m thinking of getting a centre speaker to see if I can get more out of the mids, I’m experimenting to see if I can get the most out of my cheap budget system without having to spend $20,000 on cables lol

hehe Funny. I had an Onix CDP back in the day. That was one of those brands that you knew was going to float away. With some companies, their fate is obvious. Others either die a slow death, or become a shell of their former selves. From what I can tell, Iotavx doesn't plan on going anywhere anytime soon. This was something I vetted before moving forward with the review. But let's face it, it's a saturated market and survival can be tough. I wish them well.

Hello there Sean, I just received my iotavx SA3 yesterday. I must say , I am very disappointed with the outcome. Seems like they sent me a defective product or perhaps someone else's return unit. After watching your review I was so excited to get my hands and ears on one. No signal from the left channel at all. (2 sets of cable and 3 sets of speakers ) Headphone output also cant feed my headphones with healthy signal from both channel at the same time. only one side (either left or right) only works when I move the headphone jack. Product being shipped out of England I had high hopes. but I was more satisfied with the products I received from China. ( couple of tube amps) At this point I can only hope that, they provide easy return service and quick refund. I hope my problem can also help people out on your channel.

[@BWWGL9]

[@TRPD]

I didn't know you were into SKXs. Good review!

[@orwhat24]

So it would be great with the new Klipsch 600 - but can it drive the new Maggie LRS????? I always appreciate it when reviewers describe the rest of the system they used for the review, because I bet lots of things sound great when the rest of the system is high end, that might not be so stellar when my old speakers and CD player are powered by the super little price effective amp. Also, I find it helpful when products are compared, just to help with frame of reference, knowing its not an absolute thing. The best current example for me is that SG raved over the Klipsch RP-600M Bookshelf powered by the NAD and also raved about the Maggie LRS powered by the Schiitt. Sure, the total systems are about 100% apart in price, more or less, but the Klipsch RP-600M and the Maggie LRS are only a hundred bucks apart. Being close in price, but very different in terms of power and space usage, I'd love to hear an experienced reviewer get into the weeds of how much enjoyment is to squeezed out of the various combos. But that's just me. I enjoy the reviews from SG and Zero a lot!!!! So thanks for that.

[@ZeroFidelity]

Reviewing gear certainly isn't easy. That said, I appreciate the feedback. I like what Steve does. He is one of the few people on this platform who isn't in it for the cash. To answer your question about the SA3: I can confirm that it forms a very good synergy with the Klipsch. Since I haven't heard the new Maggies however, I cannot say how that comobo will go. I'd imagine that it would sound good at moderate to low volumes, particularly on simple music. I also think its safe to say that the Maggies will respond best to a bit more power, so I wouldn't be surprised if you'd end up with the SA-3 | PA-3 combo.

[@orwhat24]

Zero Fidelity thanks for the comment. You and Steve are my morning coffee companions! Ah!!!! PA 3 is the power unit only! Got it. Thanks for the idea.

[@freedomdance7601]

Manos Fragkiadakis I truly wish he would compare the 6006 to the arcam or this

[@nc3419]

Like the review, looks like it beats out the The Denon PMA800NE you reviewed for performance. Also looking at Audiolab 6000a which is still more money, but how would it compare? That's the problem of not being able to do side by side comparisons locally. One big issue is ...what if you lose that remote? Seems there are no onboard controls for the IOTAVX SA3, so having the remote last without fail and not losing it is important in this amps' operation. Having control knobs would be a nice feature. So, is the SQ closer to high end or just class leading budget? Also, while I know you didn't review the digital front end, it would be nice to get a sense of performance, rounded, large stage, sharp...etc. Not all of us want to buy an independent dac for $$$.

[@Chiroman527]

Sean, a very good non convoluted review. As you depict here and in other KZbin vids, the selection available to audiophiliac wanna bees, is maddening. Your info is concise and well appreciated. I have a question... is there an Animal out there to allow me to switch my speaker connections ( 2 pairs of different bookshelf speakers [ my bad..... 1 pair of Fluance Signature Series Surround HiFi Bookshelf speakers and 1 pair of Elac Debuts 6.2) without switching connections from my Denon DRA-800H Receiver and connect the speakers to this new OIKA Integrated Amp?
