Hi. The op amps are- 2 control the right and left RCAs ( close to the knob)… 2 control the right and left XLRs … and 1 control the subwoofer output! So there is no way that all of the 5 Op amps are working at the same time
My first ever amp was a fosi Q4. It was a nice little baby starter amp to get into the audiophile scene. Im currently rocking a Xduoo ta-10r and Fiio k7 all thanks to zeos' bombasstastic recommendations. Fosi will always have a place in my heart, I'm pretty happy seeing so many people appreciate their products and seeing how well they are doing now.
Yup, i knew these would come out but i couldn't wait. Now u can buy a 16 channel processor, 15 of these and some subs for pretty cheap comparatively. Lucky for people building theaters right now.
Ok. Now I see where you are coming from. Though I suspect that there may be technical dificulties in running the TPA3255 chip in bridged mode. However, the notion of a future iteration of the ZA3 that includes a power meter, is to be welcomed. I will be taking delivery of 2x ZA3's over the next few days to play with for now. Regards.
MYTH: MOST OP AMPS ARE COMPATIBLE - Op amps are complex devices. While many have the same pin configuration making it appear you can simply substitute one for another, that’s often not the case. They’re optimized for different input bias values, configurations, gains, feedback circuits, load impedances, quiescent currents, speeds/bandwidths, compensation values, operating voltages, noise trade-offs, etc. But some audiophiles can’t be bothered by, or don’t understand, all those details. So they simply swap them out without changing anything else in the circuit. Many have a favorite op amp or two they like to use in most everything without considering if it’s a good match. It’s like the old quote “when you have only a hammer everything looks like a nail”. But that just doesn’t work for op amps. And, not surprisingly, some op amps do better than others when you ignore their requirements. Again, this is a lot like the Second Grain Of Truth above. If you use a given op amp incorrectly, it may well sound different. But it’s not the op amp’s fault. The person misusing it is creating the audible differences. MYTH: OP AMP UPGRADES ARE USUALLY WORTHWHILE - The forums are full of posts from people who buy some perfectly nice piece of audio gear, open it up, discover the manufacture used a “cheap 5532” op amp, and they promptly pop in something much more expensive and exotic to “improve the sound”. These are usually people who lack the test equipment to have any idea if their op amp swaps help, hurt, or are just a waste of money. They simply use their ears, in highly biased sighted listening, and draw all sorts of erroneous conclusions. I know of op amp swaps causing potentially harmful oscillation. Someone might hear ultrasonic artifacts from the oscillation as “newfound detail” when, in reality, they have unwittingly created a radio transmitter. And this isn’t as rare as you might think because of the “faster is better” mentality. nwavguy.blogspot.com/2011/08/op-amps-myths-facts.html
Thanks for the review Z, grabbing two of these to upgrade my setup. Agree on the alcohol tip, though 91% is the highest available in my area. Still, good enough. As for monitors, distilled water is all that's needed, no fancy "monitor cleaner". Distilled water cleans nicely and doesn't leave streaks. I bought a monster brand bottle of monitor cleaner years ago and it doesn't clean any better or differently than the distilled water. I keep a small spritz bottle of each at my desk. I use magicfiber brand cloths and they're amazing. My wife introduced me to posca markers a while back; they're amazing. Merry Christmas and Happy New Year!
All things being equal. How would these compare with an old school set up (i.e. two, separate, bridged Crown Crown XLi800's)? The cost is a little more and they're bigger, but crowns are rugged and time test.
Hello, I like your review, it felt familiar. I just bought a dual 1219 , my first personal turntable, I wanted vintage quality and not something new. I got it with 3 headshell and 3 different cartridges (nothing to expensive, just classics and a new model) and I like switching so quick. I now found back that feeling of putting an album and listening to it until the end, and... IT FEELS SO QUIIIIICK! i'm always "ho, over already...". I enjoy the music completely different since I got this turntable and I keep buying vynils, I will consider getting a streamer but I just don't want to have that feeling that music is endless, and at a certain point you lose interest in what you are listening to. Vynil feels so good and only have a entry level phonopreamp that costed me 25€... and a yamaha sound bar but it is such a difference. Upgrading slowly over the next months, it's a quest I like it, and I'm so happy music is even more interesting and moving me just by listening to it all the way through albums and not switching from song to song.
I had to laugh at your comment at the Gear Wrench set. I have it too and immediately saw it and thought, man I love that little kit! It makes a great little set for indoors.
Maybe a dumb question, how does the volume control work when you run as monoblocks and each has a volume control? How do you get left and right levels the same?
@@ZReviews When I first created the 3 channel home theater speaker experience back in the early 1980's (before Dolby did it), I used 3 bridgable Denon amps on Dynaudio drivers It still beats the crap out of any 3 channel Dolby System even today I have always used 91% isopropyl as 99% will absorb water from the atmosphere once it is opened The inactive ingredient in 91% isopropyl is pure water and less dangerous than 99% (see warnings on label)
Does the ZA3 perform the same/better than the Aiyima A07 Max in terms of sound quality? How does the ZA3 compare to the Topping LA90 Discrete in terms of sound quality?
This is not giving 200W into 8ohms in mono. Williston Audio Labs measured it and the power is around 100W for 8ohms both for stereo and mono. So nobody go buying this thing, or worse multiple of this thing, expecting a 200W monoblock. This is false advertising.
??? Don't lie. Williston Audio Labs measured 219W at 4 ohms and 294W at 2 ohms. He was impressed by the power of this little amp and its great sound quality.
Two of these for $350 and you can bi-amp your 2-way speakers. Four and bi-amp in monoblock configuration for $800. Active XO for $200 and you are set. A truly excellent bargain with Stereophile Class C sound for 1/20th of the price.
Very interesting little amp. Would love to swap the 48v power supply with a high end version. But that would be hard to find. (most are 5 to 12v) Thanks!!!
Hi. I have to correct something… The 5 op amps work like this: 2 control the right and left RCAs ( close to the knob)… 2 control the right and left XLRs … and 1 control the subwoofer output! So there is no way that all of the 5 Op amps are working at the same time on the same signal… know your stuff
Dumb question but if I was using these as monoblocks with the preouts on my receiver would I just set the volume on the fosi to max or would that risk blowing stuff up?
I’ve been eyeing this Fosi to pair with my Klipsch RP 600M II, iFi Zen Phono 3, and turntable. With the ZA3 not having tone controls, is there something that you’d recommend adding to adjust treble/bass or an eq?
I'm looking to upgrade from my Adam audio T5V's, which have been my goto speaker for years. This seems like a good amp! I'm using a IFI Zen dac v2. Can anyone recommend me some (affordable) speakers with this combination?
When back in stock I plan to grab one for now. One big reason is the rare feature of a power amp having two selectable inputs. I will run a record player through RCA and a DAC through XLR. Looking at Fosi's wiring schemes for stereo vs. mono block it might be suggesting that when running mono you lose that rare selectable input feature. Anyone with these in mono, can you confirm or refute that?
I guess I’m old school but I am not sold on class d really love my class ab id love to see actual measurements thd levels ratings at 20-20 hz not 1kHz etc etc
Class D is really something for you to try out. It’s different than AB and you have to just hear it and see if one works with your speakers in a way you are pleased with.
So my dilma is, i have a yamaha DSP-AX1 and a Yamaha MX-1000, would a pair of these running mono each with opamp mod and a nice dac or an preamp equal or better the sq of my setup. I want to run a pair of Martin Logan SL speakers. I wonder if they plan to make a more powerful version, say a 500watts mono?
What about the smsl a300 you reviewed a while ago? it also could work as monoblocks. Are these better? With the opamp swap i think the are more or less the same price. This one has xlr but everything else feature related the a300 wins (high pass filter, remote, eq options and tone controls, etc.)
I'm considering buying a Fosi ZA3 but I'm not sure if it has HISS Noise when there's no signal input. I would appreciate it if you would answer my questions. Advance Thanks..
After doing some digging 2 fosi amps in mono hardly do anything with high impedance headphones like the Tungstens. They aren't bridgeable in mono above 2ohms so they only play one channel at 9w gain at 8ohms so with the Tungsten your gain is like .025w.
I am no longer recommending these Class D with Headphones directly. There are things happening up in the 40khz range you can't hear but might break something.
@@JonMoralesLA I like dynamics more than anything and most people I have demonstrated my systems too have appreciated that as well. When a system can rocks yours socks off without distortion it’s pretty amazing. Dedicated power supplies and amps running mono will help with that so you get a good bang for the buck.
Dude, you HAVE to do a review of Fosi Audio BT30D Pro . I watched a channel called LIFE IN SPEED Mike Angels . He powered 2 5Foot floor speakers with 415 inch speakers and 15inch subs and it ripped. Also only on 32V psu. Love the channel btw.
I loved Z Reviews several years ago and then somehow they fell out of my algorithm and I hadn't seen very many of them in a long time. So, weird question for the community: What does Z like in about $150 headphones? I'd love to have a pair of Meze 109's but my budget won't reach anywhere near that far. Amp is an SMSL AO-300, brand new. TIA.
I was thinking of the new Smsl ao300 which has a built in dac but now i see fosi za3, just wanted to know if it can drive q acoustics 3050i tower or i should look elsewhere?
ao 300 turns off at higher volume, zeos talks about it in the review, I had ao 200mk2 and it was not as good as the 3255 amplifiers. buy aiyima 07 max or fosi za3 and some dac plus wimm pro. I have this q3050i, if you want something more expensive, buy topping pa7, that's what I did.
@@immanuelsuresh7739 For me, the pa7 topping is better than my Yamaha a-s 1100 amplifier, I sold it and the pa7 stayed, try the fosi za3, if you don't like it, return it.
Is it not possible to run a 2.2 monoblock speaker system? 2 speakers and 2 subs, one of each on each amp? Or does it not send a signal out from the sub out if it's monoblocked?
About that stereo/mono switch .... Reconfiguring the TPA3255 from 2xBTL to 1xPBTL is not guarded by the chip's protection circuits. This means that it is not safe to flip that switch while music is playing... it will fault the amp, shutting it down, and it may not come back on! Before your viewers run into trouble... you really should make a video showing them what happens when you do.
Z, in the description you mention THESE op amps, meaning that's the op amps you had input? Seriously thinking about swapping op amps after I get my units because this sounds convincing. I can't really decide on BurrBrown or Sparkos. The Burson option seems good too.
This is gonna be a doozy of a system when i get done being too poor to buy nice stuff. I have a set of old Sansui cabinets that im going to transform into a doominator set up. If i can find all the right drivers.
Just wait till you get the Aiyima A70 which has XLR inputs and variable sub out 12v trigger etc It's on preorder and will ship march 20th and is the most expensive AMP ever from Aiyima at $189 Cant wait to get my hands on one
It looks like it is not a bridgeable mono block. When it was tested on a dyno it made 2x 95wrms @ 8 ohm's and 2x 175wrms @ 4 ohms OR 1x 109wrms @ 8ohm's and 1x 190wrms @ 4ohm's with the 48v brick. When running this amp in mono it looks like all it is doing is shutting down one channel to protect it. By buying 2 and running them in mono all you are gaining is 15w. Hardly worth it? ruclips.net/video/fICMe0QvYrE/видео.html
Not exactly a preferred terminology regarding the possibility of a mischievous or curious heart flicking the mono/stereo but yes mate, not the best locale.
** 36:52 Please be VERY cautious using any Class D amplifier for Headphones. There has been studies done recently showing an issue that can damage headphones AND ears if things go wrong. See @goldensound for details
New Micca MB42X G2 is out. Be interested to see how it matches with the newer class D amps.
NOTE :: You only need ONE Op-Amp for Monoblock use - Put in Right Channel and you are GTG.
So you mentioned you pulled 3/5 op-amps and replaced them with the Oracle II 02 op-amps, those spots are the 3 that have to be yanked for a full swap yeah? What were those spots? Left, right, and an op-amps for specifically the XLR ports?
Which one is it on the layout mate?
Adding to my comment, Fosi has a video detailing the op-amps and where they are as well as what they provide power to.
Yeah I swapped the XLR one but I didn't isolate that to test the change. So i put it back to normal for now. I might test later.
Hi. The op amps are- 2 control the right and left RCAs ( close to the knob)… 2 control the right and left XLRs … and 1 control the subwoofer output! So there is no way that all of the 5 Op amps are working at the same time
Fosi hit the home run . I got mine from quick starter yesterday. Initially positive,it gives good sound for non critical listening.
I'd argue for critical as well. Depending on what you are pushing.

Hey Zeos how would I run these in Mono? Do I buy 2 or 3 of them? I would like to use them for my Tungsten. Would this work?
My first ever amp was a fosi Q4. It was a nice little baby starter amp to get into the audiophile scene. Im currently rocking a Xduoo ta-10r and Fiio k7 all thanks to zeos' bombasstastic recommendations.
Fosi will always have a place in my heart, I'm pretty happy seeing so many people appreciate their products and seeing how well they are doing now.
The kiss at 5:39 leads me to believe I’ll be buying a few of these.
The Chef's Kiss sealed the deal for me. I bought 2 soon after.
@3:39 that is not how to compute power in an amp. 48 volts power supply doesn’t mean 48 volts coming out to the speaker.
So if the orchard audio mono blocks are a 10/10, what do these get out of 10? Would they compete if the op amps were swapped out for better ones?
Yup, i knew these would come out but i couldn't wait. Now u can buy a 16 channel processor, 15 of these and some subs for pretty cheap comparatively. Lucky for people building theaters right now.
Or 8 of these if you don't need the extra OOMPF
The most expensive part to these Fosi’s are all the wall outlets😳
Great amps man. Love mine
So buy 4 of these and bi-amp a pair of speakers.?
I'm waiting for the actual mono block versions with VU meters on the front, you know they are coming in 2024.
Interesting. How good is your info? Where did you find this out?
Thanks.
@philipkershaw7918 it's a prediction...these ones sold out in 24 hours....people want the mono block version...it is coming. I guarantee it.
Now you have me somewhat confused. The ZA3 is a monoblock version, in that it runs in a stereo or mono configuration.
@philipkershaw7918 no its bridgable....there is a difference....a true mononlock is not capable of stereo...
Ok. Now I see where you are coming from. Though I suspect that there may be technical dificulties in running the TPA3255 chip in bridged mode.
However, the notion of a future iteration of the ZA3 that includes a power meter, is to be welcomed.
I will be taking delivery of 2x ZA3's over the next few days to play with for now.
Regards.

Great review 👍. The Z3a could be a giant killer. Do the in think it can drive the Klipsch R7 ii ? Mono blocks, of course😊
I'd love to see that home set-up, with 7 of these!
You could use a hole punch to cut a hole in the case above the op amps.
All things being equal. How would these compare with an old school set up (i.e. two, separate, bridged Crown Crown XLi800's)? The cost is a little more and they're bigger, but crowns are rugged and time test.
I gotta get a couple of these, with a good preamp with gain and tone controls they should hang with nearly anything from what i gather.
One question. Using two in mono. Would it also make a stereo sub setup?

So hypothetically, a person could use these to run a monoblocked Doomstack for each channel in a theater?
That is what I am doing for 3/7 channels in my theater! And you only need ONE op-amp if you do the monoblock, the right side.

Amazing! How do you set the volume on the 2 units when having to match volume? Do you max it out on both and then set the volume from the pre?
Exactly. Unless you like fiddlin'

In monoblock mode, would you need to run two subwoofers if you were connecting them to the ZA3 and not out of a preamp?
I believe you only need to send one of the amps Sub-Outs to run only one subwoofer.
@albe1796 Yeah but its only pushing the bass info from one channel. So its weird.
I'd love to hear a review from you on Buckeye Amps Hypex mono-bois
They just raw boards? Cool but hard to review/sell to normies.
No, they are fully assembled amps. I have a 3-channel Bukeye Amp. No regrets
I'am thinking of making my HomeGrown loudspeakers active, by these as monobloks, always Likes your tests. 😊👍
This or the Sabaj A10a?
Imagine a version 2.0 with just HDMI input to connect to tv arc hdmi to control with tv remote
I was thinking of the new Smsl ao300 which has a built in dac but now i see fosi za3, just wanted to know if it can drive q acoustics 3050i tower or i should look elsewhere?
ao 300 turns off at higher volume, zeos talks about it in the review, I had ao 200mk2 and it was not as good as the 3255 amplifiers. buy aiyima 07 max or fosi za3 and some dac plus wimm pro. I have this q3050i, if you want something more expensive, buy topping pa7, that's what I did.
@@AdamMrozek84 thanks for the update, or shall I go for class AB like marantz pm 6007? Will it sound better with q3050i?
@@immanuelsuresh7739 For me, the pa7 topping is better than my Yamaha a-s 1100 amplifier, I sold it and the pa7 stayed, try the fosi za3, if you don't like it, return it.
Is it not possible to run a 2.2 monoblock speaker system? 2 speakers and 2 subs, one of each on each amp? Or does it not send a signal out from the sub out if it's monoblocked?
I haven't tested that. It SHOULD be possible.
@@ZReviews Live stream from Fosi a couple days ago happened, according to them, it can be done, head-person mentioned he was going to message ya.
I may get one of those to replace my drsk amp.
Hello Does the Fosi Za3 support an 8 ohm speaker?
Yes.
@@ZReviews Thank you.
I hope I love anything as much as Z loves monoblocking
You gotta try the new Cerwin-Vega LA series speakers...they will blow you away for their price .
Haven't touched CV in a hot minute
@@ZReviewsHello, can you hear the hiss from the tweeter up close like in Fosi v3? Best regards
@@AdamMrozek84This…what’s the noise floor on these when nothing is playing
Actually...Thieaudio is obsessed with Roll Royce model names. Ghost...Wraith...etc.
About that stereo/mono switch .... Reconfiguring the TPA3255 from 2xBTL to 1xPBTL is not guarded by the chip's protection circuits.
This means that it is not safe to flip that switch while music is playing... it will fault the amp, shutting it down, and it may not come back on! Before your viewers run into trouble... you really should make a video showing them what happens when you do.
Sold! I bought 33 of them
What the FUUUUU are you doin' bro?
MOdhOusE tUnGSteNs!! Can't wait to get a couple pairs for the wife and I.
DO IT
Z, in the description you mention THESE op amps, meaning that's the op amps you had input? Seriously thinking about swapping op amps after I get my units because this sounds convincing. I can't really decide on BurrBrown or Sparkos. The Burson option seems good too.
No the THESE ones are ones I found but never tried. They look wild.
The Oracle ones are the ones I bought for it.
lul theyre expensive though
Nice keyboard Zeos, hope you are enjoying the thock 😁
Is this a good match for the Buchardt P300?
Yes and yes.
Yes and yes. Especially in mono.
To my understanding, going monoblocks and using a sub out just necessitates two subs (one for each amp). I could be mistaken though.
I happen to have two matching 12" jamo subs to test with. Just need to get 2 more amps so I don't need to pull apart my theater again.
Off topic……..BTR15 review when??? 👀
Started playing with it a few days ago.
This is gonna be a doozy of a system when i get done being too poor to buy nice stuff.
I have a set of old Sansui cabinets that im going to transform into a doominator set up. If i can find all the right drivers.
Is it better than smsl a300? good job, as always
Yeah all these new Fosi amps are just killin' it.
Hey Z I'm waiting for the Tungsten (single and double-sided) review! Would this monoblock setup be better than a Jotunheim 2 or a Mjolnir 3?
Would love to know this as well
200W - So meaning 100w x 2 and is that in RMS?
Most normal amps are reported in RMS. So yes
Fiio JT1 when ?
13:24 Damnit, this made me laugh.
Just wait till you get the Aiyima A70 which has XLR inputs and variable sub out 12v trigger etc
It's on preorder and will ship march 20th and is the most expensive AMP ever from Aiyima at $189
Cant wait to get my hands on one
It looks like it is not a bridgeable mono block. When it was tested on a dyno it made 2x 95wrms @ 8 ohm's and 2x 175wrms @ 4 ohms OR 1x 109wrms @ 8ohm's and 1x 190wrms @ 4ohm's with the 48v brick. When running this amp in mono it looks like all it is doing is shutting down one channel to protect it. By buying 2 and running them in mono all you are gaining is 15w. Hardly worth it? ruclips.net/video/fICMe0QvYrE/видео.html
I’m waiting for the supreme commander Xi edition!
Why do you sound like Robert Downy Jr? Or AKA Tony Stark?
Confidence.
Not exactly a preferred terminology regarding the possibility of a mischievous or curious heart flicking the mono/stereo but yes mate, not the best locale.
Ok this gave me a chub
thanks....
I need a company called Fuch to come out so i can have a fuck shit stack
put it with 2 ohms rated speakers and they will explode with quality as monoblocks
Who even has speakers of 2Ω?
me, handmade@@ZReviews
