Fosi Audio V3 Mini Hi-fi Stereo Amp

Best Feature:Functions as an amplifier should, has a pre-out. Haven’t tested if this is the 2024 version that has the improved pre-out.Product Quality:Sturdy chassis. The volume knob has a nice tactile click between the powered on and off position, and turns very smoothly. Would have loved the orange knob though.Performance:Plenty of power for the price. The 48V power supply is an instant upgrade for those who want to use these for more demanding speaker setups.These are apparently exceptional to the point they can power the Wharfd*le L*ntons. Class A/B sound for the price of Class D. Also opens up the path to swap op amps to the highly praised Burson and Sparkos.However, I bought this to power a pair of budget passive desktop speakers that originally came ... MoreBest Feature:Functions as an amplifier should, has a pre-out.

I would say this is a fairly good combination as the Fosi Audio V3’s internal op amp objectively slightly lacks a bit of the low-end frequency response, and I think that a warmer sounding amp might introduce harmonic distortion with my speakers’ stock tuning and relatively flat anechoic response.With this unexpectedly good pairing, I’m able to extract a much better sound and feel that I’m able to bring these budget speakers to life at such a good price.Verdict: Wide soundstage, clear imaging and separation with a slight lack of the low end. A subwoofer can fill the space left in the low end but it isn’t required.Will update the review with images once I’ve cleaned up some clutter!

Not 300w per channel but great amp none the less

even if it had a 48V 10amp power supply 300w RMS would be impossible. Don't let that scare you though it is a fantastic amp for the money. I know they say you get what you pay for but I feel like you could pay 5X and not get a better amp. The low frequency response is impressive, the mids and highs are clear and well defined, stereo separation is great. This thing is rivaling a Luxman M-117 (not quite that level but wow) I can give it respect. Don't pass it up unless you just have to have more power. you will not be disappointed unless you have unrealistic expectations.
