[@genesxse3744]

Randy, just wanted to say thanks for the advice the ss3602's do provide excellent clarity and separation from the originals that were installed. The over all installation was easy to perform and took about 5-6 mins. Keep up the great work as the cheapaudioman it is truly appreciated.

[@jamms2966]

@cheapaudioman - I followed your guide & "rolled" the factory op amps for the Sparkos. It wasn't hard to do & my wife & I both wholeheartedly agree the sound is MUCH better! I also swapped out the factory power supply for the DROK 48v 10A so I cant be sure of the results but our SVS Ultra Bookshelfs are for sure louder as well. Thanks for the great content

[@ount252]

A bit late, but for posterity sake I learned that you must use dual circuit OP amps in the AO7 - In other words the SS3601 will not work, you must use the SS3602 (which is what Randy is using in the video). Sparkos did an exchange credit for me and after paying the difference I've got the SS3602s headed my way. Don't make my mistake!

[@moss8448]

be nice to hear what (in your opinion) differences it made with the SS3602s once you got 'em

[@ount252]

@@moss8448 It made the Aiyima A07 a bit clearer on a pair of Jamo S803s (which sounded a bit bloated and muddy before - not the A07's fault, those 803s just aren't great speakers). It definitely livened things up a bit and made for a bigger larger soundstage. Having said that, I'm not sure it's worth the money tbh. For the $160 for the two discrete op amp chips and $80 for the A07 - at $240 you have a lot of other options out there would would probably sound better and give you more clean power. If you are using the op amps on a different product (I know there are plenty of applications), then I'd say maybe they are worth it depending on what you are doing.

[@carnut374]

@@ount252 I think one of these other things to consider though is form factor. You could buy something else in that $250 range but at least for me right now, the A07 is just the right size. Also as another data point, I just did the swap to the SS3602's yesterday and there is definitely a difference in the sound. There was a jump in detail that surprised me because I thought I had it pretty good already (speakers are Polk R100s,) and the soundstage did get bigger particularly front to back from what I could hear.

I have the Sparkos ss-3602's inside my HP amp (Gustard H20) and they're very good sounding pieces. I am also trying out the Burson v6 Vivids in comparison and they're great too (but in my amp the Sparkos are slightly better - in another component it may be the exact opposite). This is a relatively cheap mod to upgrade SQ on any component that has compatible opamps and DIP8 sockets - much cheaper than buying a different component and most discrete opamps stomp IC opamps, IMO. Be careful to make sure which types of opamps are inside of your component before you replace them - ie: single or duals, opamp inter-compatibility, and orientation. Happy listening...

I recently viewed your video about the $80 Amp and decided to give one a try. I would like to thank you for the info you provided, here is a copy of the review I left about the Neoteck Bluetooth 5.0 Stereo amp. I purchased. Title: The surprise was on me! I purchased this amp for my home office as an experiment, well the surprise was on me. I never expected that this little amp would perform so well. I hooked it up to my Polk S60 towers, this little amp powered them surprisingly well. I then hooked it up to a pair of Energy Connoisseur C3 book-shelf speakers I had stored away and what a surprise I got. The Neoteck Bluetooth 5.0 Stereo amp was where it is supposed to be. I had planned to sell these speakers, I've had a complete change of heart! This little amp breathed new life into them, I had forgotten just how good these speakers could sound. The Neoteck Bluetooth 5.0 Stereo amp punches well above it's weight class. I spent 1 1/2 days listening to all types of music on this combination and I'm still amazed with the sound quality. I highly recommend the Neoteck Bluetooth 5.0 Stereo amp for a small room or office, you will not be disappointed!

I upgraded my 1984 Denon DCD 1500 II CD player with Texas Instruments op amps. The sound quality improvement was even greater than the new DAC & new capacitors. I now have a magnificent Audiofool quality CD player that started out as a $5.00 thrift store score.

[@MrBenherrmann]

Hey gang....just to let you know, I installed these Sparkos op-amps in my Aiyima A08 also (now do be advised though that the A08 takes 3 of them), and again - a major sound change for the better ensued! The amp now (also) has that class AB sound - that is warmer and more dynamic. Now do be advised that with the A08, it's a bit more tricky. The top does NOT come off. Remove only the front panel (where you'll see the 3 op-amps right towards the front for easy access), unscrew the 4 screws, pull off the volume knob, and unscrew the nut that holds the volume knob control ring in place tightly. Then you pull off the front (it won't come all the way off because wires are attached). Now, reach in carefully and remove the stock 3 op-amps (use tweezers - they work the best), and then you just replace them with the Sparkos ones. At first, I tried taking off the entire top - can't be done, and you have to be very careful because you could damage the unit. Again though - it's another wonderful upgrade, bringing the A08 to amplifier audio levels that usually you'd have to pay 10 times as much for, or more. Enough said! Thanks again to Randy for making us aware of upgrades like this.

[@sarahjh785]

I swear, I'm dumping entirely too much money into Sparkos Labs. I put the Sparkos Labs Op Amps into both my Aiyima 07 and 08 amps, and also, I put one in my inexpensive FX-Audio DAC X6 Mk II DAC, where it made an appreciable sonic difference. I've got two more inexpensive Chinese amps coming and between the both of them, they will take an additional 6 op amp change-outs. Damn, I'm goin' broke here.

[@JoshFisher567]

Great video, especially for people who realize the benefit of something like this. Having built or repaired computers, laptops, and smart phones, this looks no harder than swapping out memory in a computer. You just have to make sure you plug it in the right way as computer memory is slotted to not allow you to insert it the wrong way. Laptops aren't fun to work on and smartphones just plain suc I'm to try and repair. Would this work with the Aiyima A300? If so, would it be the same chip based off amp that the A07 uses or would it be a different chip? I can probably figure it out in a few Google searches but obviously you would know, or figure out way quicker than I could. Also, thanks for all your tips in various other videos. I was looking for some bookshelf speakers. While I wasn't planning to spend what I did on the Elac Uni 2 B52's, I'm glad I did and I've only had them for 9 or 10 days so still breaking them in. They didn't amaze me out of the box but they have been getting better every day. Vocals are crisp and clear. It's just balanced as you stated over and over in various videos. I'm not sure why people think speaker break in isn't real. Think about it, popular materials for speaker cones are paper, metal, plastic, and aramid fiber. Plastic is obviously going to stretch out a bit over time. Paper has more variables. Aluminum is woven very tightly so it will stretch a bit over time. I don't believe I've had a speaker that uses aramid fiber. Personally, I believe speaker manufacturers make the woven cone material slightly tighter than it should be for this very reason. I also have the Sony HT-A7000 and initially I was going to return it. Out of the box. I wasn't amazed. Then Sony announced new rears which are 2 smaller A9'S that run on battery for 10 hours (per Sony) and they are bringing the same software used in the A9's. Initially I didn't get a great Atmos effect but I swear, one day it's like it turned into a completely different sounding speaker. All the sudden I was hearing sounds that were coming 4ft behind my head. A wall is 1 door away so that was new. Anyway, it wasn't great for music, which is why I got the Elac's, Aiyima A300 and the iFi signature one, mainly because it had the right inputs/outputs I needed for my setup. Now I can hook the optical out from my TV to the iFi and with some tinkering around with time delays, get everything to synch up perfectly so it's the best of both worlds for movies. Music is just Elac's. I do wish the wireless Sony subwoofer did have an input but I will just get sub down the line.

[@naastradamus]

Hi Randy, I'm running the Aiyima A07 with a Meanwell 48V 7.3 Amp psu. I have an Akitika amplifier on-order. Wondering how much of a difference you hear between your A07 and the Akitika, if there's any definitive sound signatures or any blatant differences. Is it mainly just instrument separation, or are there other sonic attributes you always notice?

[@naastradamus]

Since I've now received my Akitika GT-102 Z4, I'll answer my own question: ...In a nutshell, sonically, the Akitika is more visceral to me. First thing I noticed was electric guitars sounded different. More like the real thing (I've spent countless hours with guitars in-person jamming with friends and in concerts). They just seemed to come alive a bit more than I've heard previously. Example: Tom Petty Wildflowers album is where the guitars first became more present. But today I found Nirvana's In Utero album sounding the best I've ever heard. EVERY instrument. I've always felt it wasn't as an enjoyable production compared to Nevermind, but today it blew me away. It simply rocked with that visceral presence that I mentioned earlier. In addition, I now understand what Randy has said about how a great amplifier can help soundstage. It was great with the A07. It's even better now. Particularly instrument separation. I'm very pleased with the Akitika investment even though it took a few months for it to deliver. Worth the wait. So thanks to Randy the Cheap Audio Man I've had my eyes and ears opened. Ares II DAC fed through a cheap Yamaha AVR (Pure Direct mode) to the Akitika, and the Wharfedale Linton speakers. It's a slice of heaven on earth.

[@sammybelskus1534]

Hey Randy! Do you think you could do a “Three different pairs of speakers at three drastically different price points” type of video?

[@kenzilla8096]

Hi. I also have the FX Audio tube -03. It boosts the signal, make the sound clearer and improves base. So does this do what the Op amps do or is this different?

[@EngrRomero]

Great idea of Op Amp rolling. The idea of tube rolling is to introduce more or less distortion to the audio signal. Let do it with op amp as tubes are getting more expensive.

[@RaveyDavey]

No the idea of tube rolling isn't to reduce distortion. It's to randomly swap in other tubes (normally more expensive "vintage" ones) and see if you prefer the sound afterwards. Tube amps usually have high distortion full stop. It's probably the main reason some people like them. Likewise, without testing, you've no idea if swapping a chip in will reduce distortion or increase, or mess up the rest of the circuit.

Otherwise it's kind of meaningless. Who has such good audio memory that they can listen to an amp, spend an hour or so dismantling it etc and then confidently state that it now sounds better? I sure as hell can't unless we're talking night and day differences. At best op amp rolling is going to be subtle and a single sighted comparison, hours apart is not remotely reliable.

I have taken your advice ( i think ) as best i could decipher it and purchased the IFI phono pre amp and an AIYIMA T9 and paired it with my Fluance RT85 and some sort of Bose speakers i cant recall which at this point. ANYWAY I was curious if you would recommend this upgrade for the T9 or if it could even be done? Was i right to go with the T9 or should i have gone with the A300? My only criticism of your content is that its hard to draw comparisons across like items as your videos tend to be "This is great! " or " This is not great! " but taking the time to compare where products are at across similar features / price points would be amazing . even if it was only sub 100 dollar rang 100-200 dollar rage etc. A prime example of where your videos become confusing is when it comes to the T9 and the A300, I couldn't find anything within your videos that made it clear as to which was the best choice. I hope that my criticism doesn't come across as me being an ass because i really do appreciate you doing these and doing them in a way that's entertaining as well as easy to understand for those of us that dont have a degree in audiophile. Some of us just want great sound and to talk about it with like minded folks who enjoy the hobby and you provide that safe space ! THANK YOU!

Hey Randy. Could you try these opamps on the Fx-Audio D01? It would be nice to know if they have the same effect (or different)! I was thinking of buying one as it is a device you recommended and would like to know if it would tame those high frequencies and maybe provide a more open sound. I was also wondering if upgrading the power supply (maybe one of those ifi ipower ones) would make a difference. Thanks

[@bobhopfner1226]

i did the same thing with my Fosi Audio Tube P2, sounds great! rolled tubes in it and my Nobsound NS-10T and they sound great with my DT990. I want to upgrade my sound card and drop in some Sparkos in that, maybe the larger pro-audio op amps. lots of cheap options out there these days and Sparkos makes them sound even better.

[@bingdong8571]

Awesome! Totally awesome! Alright hamilton! I've been looking for cheap amps for surrounds and this upgrade might make them good enough. Do you know of mono amps like this?

[@izumispa2993]

Randy is the BEST! So glad to be able to support his fabulous channel. It just keeps getting better and better!

[@MichaelBruceTaos]

Hey @cheapaudioman I made a video after yours. I love Sparkos and have been trying to hype them for more than a year! Thanks for this one.

[@deathstryker666]

Hey Randy, would this type of upgrade be applicable to a preamp like the Aiyima Tube T6 Pro? Great content as always!

[@martinbern4761]

5pcs

[@sloker874]

Hey Randy do you think it would be good to put 2 of these on both sides of the Aiyima A08 with a 3rd Burson V6 Classic in the middle to keep the warmth of the sound??

[@d.l.2401]

Thanks Randy, Just ordered 2 Dual OP AMPS for the FX AUDIO TUBE-03 Vacuum Tube Preamp. Replacing the Texas Instrument NE5532P OP AMPS.

[@truckyouable]

Got the Sparkos op amps in, wow! Driving restored HPM 60's, Me like! Thanks Randy.

[@smyrnianlink]

Thanks sir. Great idea.. Can I get similar results with a LM4562 ?

[@grhaggerty]

I own this amp and I put 2 Burson V6 in it and it did sound a lot better, (Tho the outside case didn't fit back on). I recently bought an $300 Emotiva class AB amp ( one that you reviewed) and the emotiva sounded better. I also bought a FX 06 tube preamp and I put a Burson iv5 and it sounds awesome. I did this from watching your past videos so keep the tips coming Randy.

[@timc_2433]

which emotive amp?

[@grhaggerty]

@@timc_2433 The emotiva Basx A2 Mini, well worth it.

[@timc_2433]

@@grhaggerty cheers. How are you enjoying it compared to other items you tried?

[@Ezees23]

Oh please, oh please, oh please...tell me where the opamps are located inside the A2M? I have the A-100 (the earlier model) and can't find the opamp locations anywhere. I've got several sets of IC and discrete opamps to try in it and it's frustrating not being able to try them our inside the A-100.

[@EJROCKER1]

Hi Thanks for your videos. I have a Fosi amp that has treble and bass knobs. I want to try using this amp for nearfield monitors. Where would you set the knobs? 12 O'clock or completely off. Thanks.

[@makarov138]

I recently bought a DAC amp about the size of a box of kitchen matches that sounds BIG as my 100W per channel Pioneer amp! Got a little tube preamp ahead of it and SHAZAM that things sound good!!

[@impuls60]

Respect for such a well used knife! Knives are great!

[@andrewc661]

Question... Shouldn't it be a single based opamp to put in that amp, Not dual? Or does it not make a difference? Thanks

[@charlesforwood8546]

I just noticed that Aiyima offers the A07 with a little more expensive Op-amp chip if you order it directly from them. The A07 normally comes with a NE5532 Op-amp and they offer a version with the LM4562. Anyone have an opinion or comment about how the LM4562 Op-amp chip compares to the NE5532? Appreciate any information. Thanks in advance. C

[@ngcolby]

I have done this swap just the other day. Not a huge improvement, but its definitely noticeable, and for $10, why not?

[@prs26]

Im glad i found this channel,,, beginning my Audiophile journey

[@MarkoVukovic0]

A great upgrade, but Sparkos discretes are a bit pricey at $80 a pop. I'm going with a pair from Orange Amps, ~$58 apiece. Already upgraded my DIYRE HC-1 headphone amp with these, that has the identical IC op-amps and the difference is amazing. They also come with sockets included.

[@scottlowell493]

Does that means the orange are as good or better? If so, how do you know?

[@MarkoVukovic0]

@@scottlowell493 as good or better than Sparkos? I don't know, as I have never tried the Sparkos. I would imagine that they will be very similar. I can tell you that they are a big improvement over the standard IC opamps.

[@Gadgetdad007]

I was wondering if it would be a good idea to get some nicely drilled small holes in the sides of the casing for ventilation or does this amp not need any ventilation?

[@ascubapro]

Hi, love the channel but here a question I’m looking for low cost amp (champagne taste beer budget) was going with the AIYIMA A300 until I saw this video which would you recommend?

[@ralphe.thompson5010]

i bit the bullet and bought the risers and chips for my ayima a07. for me, even with equalization which did improve the sound, with some rockish-songs my stock a07(paired with a AYIMA T8 PREAMP) running to DUAL polk subs paired to tsi-100s just had a 'missing middle' and slightly hissy highs and maybe bass that was disconnected in an odd way. i tweaked and tweaked and got it sounding good but was still a little unsatisfied. the sparkos do make a very noticeable difference and to me improvements. separation is definitely increased...just more space and depth to all forms of music. and that 'missing 'middle' that i was experiencing has been fixed. much more balanced sound and seamless sound now. i wasnt sure about these but i am much happier about turning the system on now and listening to music.

[@BigChungusthe3rd]

I've got the missing mids problem with my a07 and monitor audio bronze 2s. Guess I'll try the sparkos

[@GaryStanden]

I just picked up a pair of lightly used A07 amps w/32v with power supplies for $100, delivered. Wondering if the Sparkos SS3602 upgrade would be the better place to start or would a nice DAC (sub $400)? Thank you for all your content and information!

[@KillerKlipsch]

Thanks Bro, just the tip I needed

[@cheapaudioman]

thank you!

[@hobblyjig]

Have you checked out the A300 yet? I’m looking to maybe buy it but now I’m wanting ti make sure I could upgrade it later on if I did get it.

[@jeffreymakuch2493]

Would I believe it? Sure, with measurements to back it up. Sighted, non-level matched A/B tests are so prone to expectation bias, if the difference is as big as you say it will show up in measurements - the Aiyima A07 stock is a decent bang-for-buck TI3255 amplifier, but has clear shortcomings when you don't factor in price as much.

[@TheSinclairmoore]

I’d like to know how much better these opamps are compared to a cheap OPA2134 upgrade.

[@vicjames2743]

What difference did the sparco op amps have over the stock ones. Better Slew rate ???

[@brentkjernisted2215]

Can I combine the Ayima 07 with the ss3602's and connect them to a Loxjie d30 or 40 to change the sound delivered? Through the 3.5 mm output on the a07, can I listen to my Sundaras or ath-70r x headphones? Thanks

[@odwatchguy]

Thank you, Randy. I really enjoyed this upgrade review. I would never take on a Akitika or Amp Camp Amp, but this looks like something I could do successfully.

[@cheapaudioman]

you got this, Tony

[@TheSynrgy1987]

There's a lot of choices in op amps to pick from, I've used some Burson V5i-D in mine a while ago (had used them before in something else). There are cheaper options too so you can get a bunch of different ones and try them out(you may prefer the cheaper ones to the more expensive ones).

[@JoshFisher567]

@@cheapaudioman what would be a good op amp for the A300? Seems like the hardware is pretty close minus the dedicated full sub out and the XLR inputs. That and 2 modes (direct and tone). It also has an internal PSU vs external on the A07. I've enjoyed swapping out parts on many electronic devices. Especially if there is a significant upgrade in quality without spending 3x as much

[@valueofnothing2487]

An operational amplifier contains 20 transistors. A transistor can replace a single tube. The operational amplifier is a complete amplifier circuit consisting of many transistors and the ability to control many features of an amplifier.

[@jd5787]

Do you need to change the power brick for the amp after you roll the opamp? (I have a 32v brick with my a07, what shall I do if I roll the opamps?)

[@jaytruesdale5587]

Hey Randy! I was looking at the manual for the Aiyima A07 and noticed that it says the 3.5 mm jack on the back is an output! I found a cable with a stereo 3.5mm plug on one end and one RCA plug on the other end. I plugged the RCA plug in to my Sony SA-CS9 subwoofer and the other end to the AUX input on the back panel of the A07. The subwoofer started working but unfortunately only the right channel on the power amplifier had any output. Any ideas where to find the correct cable?

[@78schoolboy]

Great idea for a channel man love it

[@reconbbs360]

Just purchased a used A07 for cheap and I bought the 48v Power supply from Aiyama and the OP amps from sparkos labs. My plan is to use it as a power amp with my Integra DMT 40.7 network stereo receiver. Only reason I'm doing this is because the receiver has zero crossover/bass management and I was able to snag a M&K Miller & Kreisel LFE-3 Electronic Crossover Bass Management Box for dirt cheap. 80hz high and low pass filters. Not the most elegant solution but it should work great.

[@tapretals698]

Hi, great video. Can the Aiyima A08 Pro be swapped out ?

[@ojaiguru]

Have you cracked your T9? What are the options there? Like someone else said, you haven't mentioned it much lately.

[@manitsony6703]

Thanks for this vid. Can thia opamp be used in ayima a300. Will it sound better than topping p which has same tpa chip. Thanks.

[@christoofart]

This sounds like a cool project. Is there an exact parts list for the needed bits?

[@brendanhoffmann8402]

Nice, just ordered the sparkos op amps and risers. Hope its worth it! Just put the Sparkos in my Aiyima. They sound much more refined and rich, less muddy too.

Great hidden tips. This is hidden gem 👌

[@stuartkennedy4202]

Randy what does an upgraded power supply do for the sound improvement.

[@justspitonjeff4932]

so lets say i have a pre amplifier that is connected into a normal amplifier then output to my headphones. and both the pre amplifier and the amplifier has changable op amps. thus i am wondering if i only change the op amp in the pre amplifier. will there be any changes in sound since the headphone is connected to the amplifier instead of the pre amplifier?
