Fosi V3 Mono...when inexpensive satisfies

What speakers are you driving with them?

I've had three so far: Super Tablette, LS50, and Acoustic Zen Adagios.

My room is acoustically treated 13x14.  Basically small and not the best shape.

Which power supply are you using, and 1 or 2 power supplies? Thanks...

I have an older Fosi amp driving ls50s no problem. Those newer monoblocks should nail it. Ls50s are not easy to drive well. I also have the stereo Fosi V3 with the beefed up power supply driving a small pair of Mirage speakers in a small desktop system and could use that in my bigger systems as well I’m sure. Almost pulled the trigger on the monoblocks but not yet. Can’t go wrong for the price.

jl35, I've got two 32v/5 amp power supplies.  So about 55 watts at 8 ohms and about 120 at 4.  

mapman, isn't it kind of crazy the sound quality/price ratio of the Fosi gear?  

My friends system…

6 amplifiers… 2 x Fosi V3 and 1 Crown amp per channel. Morrison omnidirectional speakers and Morrison subwoofers.

I've never heard of Morrison speakers.  They look pretty cool.

Are they a three-way with an amp for each speakers?

This fosi mono appears to be getting praise from some picky dudes.

Fosi mono review

@audiodwebe 

Don Morrison has been hand crafting omnidirectional loudspeakers for about 50 years in Toronto ON. They were originally based on the design of the Hegeman omnidirectional speaker (Morrison was mentored by Hegeman).

The ones my buddy has in his main system are a transmission line woofer (metal) and soft dome tweeter per speaker and separate transmission line sub woofer (two boxes per channel). 

They image like NO other speaker I know of… and the Fosi V3s are replacing 70 watt class A monoblocks. They are modified with Sparko op amps and are settling in nicely.

The "golden ears" crowd are aghast! How come something so cheap can sound so good! If only they came in a bling-encrusted 100lb pair of cases with blue VU meters. 

I got a 300 wpc Fosi class D amp for an desktop system in my office. I am really impressed with the sound quality and it’s musicality. Excellent cheap streaming amplifier.

I bought a v3 for my kid's pc system to power a pair of Vienna Acoustic Bach Grands.  It's not audiophile at all and I haven't compared it to anything but I can say it's at least pretty good and it has plenty of power.  Very punchy, tight grip in the bass.

I had the stereo version and I personally didn't care for it. Trying to drive some TAD speakers which is 4 ohm and didn't run-in very long . Maybe I will try breaking in again. Good for the money though.

My monos are now driving a pair of Totem Tribe Towers.  To my ears, they sound fantastic with plenty of detail, separation, and bass.  I'll throw in some Pass or VTL gear once it's a bit cooler to do a direct comparison, but for me, the idea that a pair of monos so reasonably priced (even including the Sparkos opamps) can allow me to enjoy my tunes without having me reach for one of the other amps I have available to me says a lot.

But then maybe it just says a lot about my inability to hear like others.  

Driving Totem Forests here. Love 'em so much I wrote a big long blog, and also you might want to look at Archimago's detailed quantitative reviews, linked from my blog. 

I picked up a pair of GaN power bricks (48volt/5amp versions), as I read somewhere that GaNs improved the sound of the amps.  When I initially swapped them out, I was surprised to learn that the volume on the preamp had to be at the same level to reach the output from the speakers, per my handheld dbl meter.

That’s when I learned that I already had the 48volt/5 amp versions.  I thought I had ordered the 32 volt bricks and had never looked at the backs of them.

I did a blind test with the help of my son and preferred the older bricks.  Only ran two tests.

I then decided to let the newer bricks burn in for a while and afterwards, I think the new ones presented a blacker background with subtle improvements in the sound staging abilities.  This, however, wasn’t done blindly so take that for what it’s worth.

I’ve currently got them driving the Magnepan 1.7i and they’re sounding pretty terrific. I’ve tried the Fosi with a variety of speakers and they’ve sounded great with all of them.
