I have a Fosi P1 pre amp. I used it in my tape monitor loop as a tube buffer. With a remote control I could switch the unit in and out instantly. I honestly could not hear a difference. I turned up the bass and had an instant tone control and since my receiver didn't have a loudness control, it came in kind of handy.

[@jupitermoongauge4055]

@@jupitermoongauge4055 I did not know that. I did roll the tubes and couldn't hear any difference.

The Op Amps are what creates the sound signature. The tubes in the P1 are already just used as a low voltage (depleted plate) "bufffer" and honestly, other than gimmick, they really do nothing for the sound. The op amps are really what gives you the sound signature.

[@anthixious]

Really hoping a variant of the P3 gets made that still has tubes, but adds fully-balanced XLR in-out, ability for mono via the XLR in/outs, and the ability to daisy-chain one to another to another to another that outputs to the upcoming ZA3's XLR input for one channel so that it uses the mono outs for speakers. Therefore, the other channel of audio can repeat this process and setup. That'd be one crazy stereo system if both channels had that setup.

[@aridembo1693]

Randy, a little bit of a disappointing review. I suppose you posted this as soon as possible to coincide with the product launch. I think many V3 users would be looking at the P3 as a supplement to the V3 to add flavour to the sound of the V3. I wish you had spent a little more time discussing the sound benefits, if any, and not just doing an unboxing. Yes, it is affordable, yes it compliments the awesome V3 in build, but does it do enough to enhance the sound of the V3? does it give it that oomph that you are seeking??

[@joshdeakins1775]

So I can't speak for how the p3 pairs with the v3 but it certainly adds a live kinda sound to my older Yamaha 5.1 system. Not sure how to describe it but it's very enjoyable! I have a 15band eq that has been my preamp for a few yrs, i figured I'd want the eq no matter what but I'm an rca cable short of connecting it into the chain 😅 to my surprise I am enjoying the sound of the p3 straight into my Yamaha. I'm very happy/impressed with the p3. Excited for the ZA3 coming.

[@ianpearson8976]

I can tell you that I have the p1 and it does change the sound if pairing with amp.i originally had the fosi bt20 and now I settled on aiyima a07.its very subjective if the sound improves but it certainly changes.

[@degolemizer]

So, the "RCA Out" would go to the "In" of an old Yamaha MX50 power amp with no issues, music playing cleanly through the speakers connected to the MX50?

[@donpadawan]

Would love to see multiple inputs, auto-off feature or just tubeless solid state. There are hardly any pre amps in this class with those options for some reason.

[@fosiaudio]

Two or three inputs; If there is no signal in 10 minutes, it will shut down automatically; Treble and Bass control with bypass toggle. Right?

[@xicofaria]

Randy, your job is never over... The Fosi Audio ZA3 just out, and it looks similar but an improvement on the V3. So, the tit for tat with the Aiyima 07 MAX goes on...

[@ggroch]

Another P3 benefit specifically for some V3 owners: Added Gain (volume). The V3 has less gain than most Class D competitors...so if you have a lower output DAC or other source you may not be able to get the full output power of the V3. Several reviews of the V3 on KZbin (and most of the dissatisfied owners on Amazon) say the V3 does not have enough power. Like you say, it has plenty, but the P3 will allow you to boost the signal of your source so the V3 will reach its full output. The Aux (sub) out is also a specific benefit for V3 owners because the Aux out on the V3 is not volume controlled.

[@wegardfjeld3789]

Get a wiim instead. Better EQ, better gain and waaay better sound. This is a disappointing product even at the price range...

[@itisjustacomment]

The aux out output , can it be used for a sub, and also, can you still use the two speaker outputs while powering the sub? Or is it one or another?

[@michaelwright1602]

Douk Audio makes a little line level booster, around $35. this little booster really brings the V3 and ZA3 to live, same with the Aiyima amps.

[@jerryminor8083]

I have several of the Fosi Audio products and am having a lot of fun with them. My favorite of all is the BT30D. It has plenty of power, but is the only one I have found with a sub output. Very few reviews of it, but I love it.

[@fosiaudio]

[@ArkadiuszKurek-ki8en]

If I connect the Fosi Audio V1.0B 2 x 50W Power Amplifier with passive speakers to Fosi P3, will I be able to adjust the high and low tones that will be felt in the speakers?

3 rca inputs in a small and affordable pre-amp like this would be huge to me as well. Don’t care about BT but as you said, I get why they put it in. A digital input would be more useful than BT IMO, but an all analog system would already be a fine addition to my affordable stack

[@fosiaudio]

Thank you, suggestions received.

[@bobhopfner3812]

The V3 line out is just a pass through from the RCA inputs, seems quite a few are upset with some kind of cross talk issue because of this... Any thoughts on this issue? Seems like it was a known issue from another amp but the error was repeated in the V3...

[@barrrybarrry]

Does it send through the signal when it's turned off?

[@pnmoura]

Nice video. I am thinking in buying one of those amplifiers from Fosi. However I am a little confused about the different models. I was thinking in buying the BT20A Pro, but someone told me that it will be best if I buy the P3 in conjunction with the V3. Is it possible to pair the P3 with the BT20A Pro? or is it possible to connect them all (the V3, the P3 and the BT20A Pro)....I am confused!!! Thank you for your response! Keep up the great content.

[@rosswarren436]

I've got the BT20A Pro. Basically, it is like a cheaper version of the P3 and V3 all in one box, but the internal parts quality of course isn't as good, and it is completely solid-state. If you got the P3 and V3 you'd have no need for the BT-20A Pro. I like the BT-20A Pro for what I'm doing with it: Powering some old small Polk bookshelf speakers for use as computer speakers. Works fine for a desktop solution. If you are going to spring for the P3 and V3, I'd recommend saving up a bit more and getting the 48V power supply for the V3 so you can get more out of it. Good luck.

[@pnmoura]

Thank you very much for your response!@@rosswarren436

[@trevor_basic]

i got a p3 today. to pair with my v3. it got off to a bad start with the faceplate being upside down. but it only got worse as i hooked it up. i thought maybe i had done something wrong. but nope. it just sounded like a cheese grater. and then the EQ. are they bandpass filters? what was happening!? i know tubes need to warm up. but i have other tube based things. if i could of thrown this thing out of the widow i would of. luckly i can just return it. if someone offered to send me another one for free. i'd refuse.

[@kukeM0n5ter]

I’m using something similar in a surround sound setup however I asked a while back about using car audio twisted rca cables for interconnects. Supposedly they reduce emi/rfi. Can they be recommended over shielded cables for a cheaper solution that’s more flexible as well??? Currently I have stinger 4000’s but they are not very transparent. Like using crappy cable vs copper. Other than that there is no noise other than the faint hiss from the tube preamps which I’m sure an attenuator can fix.

[@SpirallingOut]

Keep the P3 and test it again with 2 of Fosi's new ZA3 stereo/mono amps in mono mode, when they release.

[@Bob-us9di]

One potential problem with the P3, and it's a BIG one, are the 'tone controls'. One reviewer has commented that these are treble and bass boosts - with no cut - despite the centre detents and the "+ and - " markings on the fascia. That reviewer found that the bass boosted by 12db and the treble by 6db - and flat response was both knobs turned all the way to the left. The inability to tame excess treble or bass would rule it out for a lot of people.

[@fosiaudio]

Thank you for your feedback, but I don't quite understand what do you mean by "The inability to tame excess treble or bass", do you mean the treble should be 12dB too? Or do you mean we need to add a tone bypass?

[@Bob-us9di]

@@fosiaudio Not quite - that reviewer commented that you could not turn the treble or bass down as full left rudder (as it were) is tonally neutral - so 0db on both pots.The mid-indent position is actually +3bd treble and +6db bass; and full right is +6db treble and +12db bass.

[@The-Spotlight-Kid]

I prefer those longer throw volume pots, for reasons here stated. The standard & practically always used "logarithmic resistance" vollume pots rise far too steeply in volume imo, for all vintage & modern power amp sections alike. From a typical 7 o'clock starting point, you'll get quite loud by the 9 or 10 o'clock position & possibly blow your tweeters or go into possible cone-destroying distortive clipping by the 1 or 2 o'clock position if not before in < 90'deg turn or within a 120'ish degree turn from zero volume when there's really a fully usable 300 or + degrees turn available to go from min to max vol' with a 'linear volume pot' so to me, they make perfect sense. I reckon manufacturers only stick to "Log' volume pots'" & not dare put a more sensible linear vol pot in as folk may wrongly perceive it's longer turn volume change as a lack of ultimate power, but full vollume just appears nearer to full-turn end-stop with a linear vol pot, which i'd bet this amp has. Boo to log' vol' pots, hoorah to linear vol pots. I quickly swapped my valve pre 100'k pot with hhe same but just ordered the linear version, there's always a linear well made Linear restance pot version for all sorts of non-hi fi uses, maybe for hi-fi too now, at least this amp maker woke up to sensible vol' change design

Long story short, I use tube preamps between my processor and amp. It’s a very interesting experience. Anything I can find that’s cleaner the better which is why I was asking about these amps.

So Fosi P3 + V3 = 2X (Fosi BT-20A Pro). But with the better-quality parts, that double in price might actually be 5X or so better in sound quality. Nice to know.

Bluetooth is handy out there where the wi-fi won't reach. Agree that two analog inputs would be nice, if there's room for them on the back. For standalone use, it might be better to pair the V3 with a WiiM Mini or Pro Plus and use the EQ on the WiiM as necessary.

The issue for most V3 owners is if the tubes of the P3 affects an ops amp upgraded V3 positively or negatively? Does a Sparkos upgraded V3 need the P3 which remains a single pair RCA input unit??? Preamps are supposed to offer inputs switching, but this one can't... Bluetooth is not a true high resolution input channel, and I don't use BT. It's convenient, but does not allow the P3+V3 to be optimized. After the excellence of the V3, this P3 is a meh product...

Thanks...good stuff as usual. I've always used preamps on amps with no volume controls. In cases like this, do you typically max out the amp's volume and control levels with the pre or is there some special formula? And what if you have volume/tone controls at multiple stages? For example, like many I've got a PC (with its native volume/level controls at the device level) streaming something like Amazon with its volume controls, outputting via the optical port into a tiny DAC which has its level and tone controls, into a preamp like this with level and tone controls and finally into an amp like the V3 with its controls. I've always assumed that it is best go as flat as you can and max out all the levels at each stage and do all your tuning at the preamp. Thanks for any insights.

[@D1N02]

Tubes need a bit current so i dial in the volume to where it Sounds good and then leave it there. Control main volume on the poweramp if it has a control. This is a buffer with controls. Not a pre-amp.

I got the P3 with the kickstarter campaign. Unfortunately my first one died almost immediately, but Fosi were fantastic and had a second one out to me within days. I think the fault was a single smd capacitor with a dodgy solder joint. So I can reassure anyone worried about product support. It is excellent. The P3 smooths out the slightly hard edge of the V3 and allows the flexibility of tone controls. It's a great wee unit and fun for tube rolling.

theres any op amp inside ?

[@tmdillon1969]

The V3 was a poor pairing with my CSS Torii. Even with the upgraded power source, it was very quiet. I'm going to try the V3 with a pair of highly sensitive Cerwin Vegas.

Review Aiyima AO7 Max ❤❤❤

[@Wuppie62]

If you want the V3 amp plus tone controls, buy the Fosi Audio BT20A Pro.

The aiyima t8 preamp with dac and remote has served me well for over 2 years ! $89

[@frankplissken143]

The T8 really is the perfect do-all preamp. Analog, coax and optical, Bluetooth, USB, tube, remote, headphones,dac! I love that thing.

Where Aiyima A07 MAX? )

Schiit Loki ads tone to any system…

[@aviromuziek]

a fosi pre amp(tube) or 2.1 AMP include a number of line inputs 3 -or 4 stereosets ,bt and usb-c/pc and ad arcHDMI also , remote Tone/volume controle, sub-out/level+crossover controle would be great... BUT EVEN a GREATER OPTION to MERGE a selected input with one main input for the use of music-inst or mic. to blend with a other audio source

[@fosiaudio]

Thank you for your suggestions, do you mean an amplifier like the NEOHIPO SA50? It has mic input so that you can use it for karaoke?

[@aviromuziek]

that is a little to much a karaoke toy box HAHA no more like a TG 502 NORSHING pro mini mixer but then include a p3 pre amp (the TG 502 incl BT and usb2.0 and usb-c(power and pc) but the dac is very low quality(16bit, 44.1Hz)) on the end stage you can link a fosi v3 or bt30pro ect to match you speaker setup

[@fosiaudio]

@@aviromuziek I see, what will you use such a product for?

[@aviromuziek]

Home entertainment (livingroom) , first just listen to music CD,vinyl or streaming audio ..but music lovers may also play a instrument like (e)piano organ guitar ect. and jep maybe karaoke , but also these days youtubers do live performing ,mic,camera,music, instruments i play e-piano (stagecombo,piano organ synth) and found the fosi BT20pro as a perfect amp for home use Setup in the living room and there for compact and stylies I hate the pro studio and ugly PA speakers and amps no need for a livingroom so the NORSHING desktop mixer i need to mix al together.. but hate al the connectors stand on top of it and create a big spider on the desk and the pre amp is not the best dont need al the potmeter and sliders so I suggest connectors on the back(1-cd,2-vinyl ,3- 2x2 jack in and out // 4- digital usb-c, opt. arc? BT) and MAIN OUT...On the front row 1. 4xline-in vol.controle 1-2-3 =analoge ,4 =digital/BT , underneed each vol knob a swich toggels main out or jack rec out Row 2 master volume, tone controle , mic, and HEADphone(incl.switch main or rec) the master(mix) will be internal route thru the tube amp to the main output. On top we will have the nice tube's same size as the V3m bt20 ect. but 2 units high

The op amps actually do all the amplification. The tubes are just a buffer and you could bypass the tubes and get the same output. Fosi do have a phono level preamp/headphone amp called the X4 that has tome controls and a single line level input also. Same buffer gimmick configuration for the tubes though, relying on op amps for the sound signature and amplification. I really do wish these companies, like Fosi, would give up on the pretend tube systems. Using tubes as a plate depleted (low voltage) buffer makes the tubes pretty well redundant. The amplification and all the sound processing is still done by solid state and they sound no different if you bypass the tubes. Not saying Fosi is bad, because for the price they are good, but the tubes are just a gimmick and they really need to stop doing it.

[@fosiaudio]

Thank you for your suggestion, actually we have managed to increase the working voltage of the tubes to 54V so that the tubes did amplify the signals.

[@mtinhk]

@@fosiaudio I have just ordered a P3 -- and your customer service, if I might say, is the best. However, would it be fair to say that the P3 is a hybrid preamp, since you still have a number of Texas Instruments NE5532DR opamps (I counted 4, theoretically able to output 80W @ 4ohms) working in tandem with the tubes in the amplification?

[@RobertHartmannJnr]

Two things: 1) I and all the other reviewers find the V3 rocks the bass. Do you get a ropey unit? 2) I run my V3 via an SMSL M300SE DAC/headphone amp. Multiple inputs, remote control, great headphone capabilities. $30 more at $110, yes, but wow. It performs as a better preamp. This is what Fosi should be offering.

[@wegardfjeld3789]

V3 does not rock the bass in its basic settings.... Boost it with eq and it's okey. Be serious ..

[@RobertHartmannJnr]

@@wegardfjeld3789 my V3 with the 48V PS throws more bass than my AIyima A08 and A08. You should buy one to find out.

[@fosiaudio]

Thank you for your suggestions.

It needs a remote
