Review Thoughts on the Fosi audio V3

[DougK1]

Look forward to your review even more now I’ve used one. And yes, doesn’t stand up to some of the headlines attributed to it from my experience. Still good value, but not a game changer.

Sometime this year. I've never been someone who rushes things and this trait has just got worse now I've retired

I had the volume where it is in the picture - that’s a good point, moving the volume much below that & it cuts out. Definitely not great for quiet listening via a direct line in without independent volume control,

Thank you. That’s interesting, as I’d assumed it might need to be well advanced. I’ll probably try mine later, as curiosity is getting the better of me!

Three line whip, Doug, get on with it!

I was surprised not to find these differences that others report. My initial reaction was it sounded a fraction dull or smoothed over, but that was literally a couple of hours from new.

I re-read the bench test on ASR, and 8 ohm speakers elicit a HF rise, whereas 4ohm (like my Sonus fabers) keep it ruler flat. Now I can scarcely hear above 11kHz these days anyway, but you guys might be hearing that. Just a possibility.

After attending the Bristol Show yesterday, I listened to my system for about three hours, so I have some reference points and know it isn’t ’out of whack’! (And I attended a piano recital in London on Friday night too).

I'm sure the Fosi is a good amp. But I see it like the Raspberry Pi, it's a good learning experience, and for those who want to tinker.

By the time you upgrade the power supply and op amps then you're into several hundred quid?

I think op amp ‘rolling’ is pointless on this, but harmless fun I suppose. The larger 48v ps is all you’ll need too.

I have a WiiM Pro Plus hooked up to a Mojo and a CA A1 amp from the nineties, sounds so good that visitors comment, unsolicited. Total cost £350 without speakers.
Hopefully when I upgrade from my Mordaunt M20 speakers I can enjoy an improvement, but I find them hard to fault without something to compare to.

Bravo! But this has exactly what to do with the Fosi amp?

do you think that fosi v3 48v is enough for my Technics SB-C 350? I want to use them as a beginner studio monitors (I use Cubase Elements and I study film and audio editing). I don't have the money to buy active speakers to my steinberg ur22 mk2 and i also want something small so i can keep my minimalist lookig desk.

Yes. I have previously owned this amp. It is small yet powerful and with a great sound. For the money it is excellent.

If you are after low-cost small form factor, this would be hard to beat.

also i read that i don't need such a powerfull amp for sound editing in a room like 4m x 4 m (13ft x 13ft) because the speakers would be at the end of my desk (approx 1.2m from me, each). So is a 30w amp enough for me to work in Cubase while sitting at my desk?

I’m not familiar with studio ‘desks’ or mixers, so I’m not sure what output levels the Steinberg offers you. However, the 48v power supply gives over 100 watts into your 6ohm speakers, so for desktop use the smaller 32v version should be enough.

See the chart I posted at post #9.
