Fosi Audio V3 Mono Amplifier Review

[Sokel]

FOSI have dropped this vid this morning.

Highlight of this video is the 35 years old Discman Mega Bass D-99 used as a source.
Hope the amps last as much

Measurements aside, can you honestly (=blindly) hear a difference?

No. I listened with good IEMs with my eyes closed, concentrating to hear when the different op amps changed. Quite honestly I couldn’t hear any point where they changed which at least is a tribute to how well the volume matching was handled. I’m familiar with how the brain creates difference when none exists from replicating a well known wine tasting experiment when I was a young marketing student. This is why I love ASR and also why I know people are strongly motivated to self reinforce after making a commitment such as purchasing and changing op amps.

I just said that it is within Fosi's capabilities to produce an Amp with 100+dB SINAD via RCA in. Not that it's coming.

Please Fosi 100+ Sinad on RCA.. /Blindbuy

What if it's only 90?

What if it's only 90?

Then the V3 vanilla is cheaper.

I bit on the Kickstarter earlier today, and got the 2 amp + 10A power supply bundle for 27% off. I’m curious if I’ll notice much difference vs. the Class D Pascal amp in my Parasound NewClassic 200 Integrated. I was kicking around the idea of getting a Hypex amp but this seemed to make sense for my set up and is certainly more budget-friendly.

I'm signing you up as a golden ear!

I can't hear the difference between 90 and 100.

That's kick ass!

Alpha Audio, are you serious? Please provide a link where they have good quality recordings.

All I have heard so far. It's their live events as well as their edited comparisons.

Interesting!! - I listened to his audio samples using a FIIO FH9 IEM, I preferred the sound of the AMP A; this sound is more to my liking/taste.

I have never heard any differences in this guy's comparison, except today, even if it was just a tiny bit. I preferred candidate B.

You mock me Anton D, but perhaps only a few ASR members are here for the sound quality. I am here so that the Sinad on my amplifier can assuage the burning insecurity behind my minimal masculinity as a modern day beta-male.

Eversolo seems to share some parallels and similar practices—at least listening/reacting to their customer base

So does WiiM!

How do you guys control volume with these monoblocks? Surely dont want to blast your speakers (and ears) with 250 watt on accident.

I mean there needs to be a failsafe on the source, or I wouldnt really feel comfortable.

 

[Brian Hall]

These look good, but I can't think of any reason to replace a Fosi V3 with these for my office system. It already sounds great powering a pair of Sony SSCS5 speakers.

You need a preamp of some sort with volume control.

@Fosi Audio, any plans to offer these as a bare amp board/module down the road?!

Almost right on cue, my son was playing music this afternoon and the speaker outputs on the Parasound integrated cut out and won’t come back on. Wish this had happened a little closer to the delivery of the mono blocks, but at least I know I have a solution on the way if I can’t get this thing going again. Failing that, it’s back to my crummy Yamaha AVR for awhile.

'tis a blessing

I've since backed it, for 2 + the single 10A, and very excited.

Already have two ZA3 and happy, but this one..... nice!

An informal survey of how many V3 Mono backers are upgrading from dual ZA3s would be quite interesting. There’s going to be a deluge of used ZA3s on the market in June!
