Love the small powerful amplifier

Use it for desktop pushing two power hungry job speakers and it does amazing with that. 😊. I have the 48v power adapter too so maybe that helps. The separation is awesome too

Fantastic Amplifier and Customer Service

What a great product for my application. There have been plenty of excellent reviews elsewhere about the audio performance and build quality. I've driven all kinds of speakers from Dahlquist DQ-10's to Quad ESL-63's and even some Sony SS-CS5's. Let me add my very positive opinion.
I don't think enough has been said about the excellent Customer Support. I've had my V3 since June 2023. Last week there was a loud *SNAP* sound that came from the 48V power supply, and everything wend dead. I brought up the V3 on my lab 45V power supply and it was fine. Measuring the power supply output revealed that yes, it was dead. One email to Fosi started correspondence with Summer, the support rep, and within days I received a replacement 48V power supply. No complicated paperwork, no excuses, no hassle just excellent customer support and a happy user.
Keep in mind that the power supply is not built by Fosi, yet they covered replacement under warranty. To me that is EXCELLENT customer care.
Thank you very much for the prompt and efficient actions.
