fosi audio

Hi, I have a Fosi Audio BT30D (non pro version) connected to a pair of 8 ohm 60-100w speakers. Input is RCA from desktop PC. I am happy with the audio quality and loudness. I have a small room so I drive it at 50% amp volume usually. The problem is that whenever there is no audio output the amp...

I have a Fosi BT20A pro that is measuring significantly lower voltage on one channel. With a 1kHz test tone, I’m seeing about 10v less on one channel. With a 60Hz tone, I’m seeing 24.2v on one channel and 1.3v on the other channel. I’m still fairly new to this, but given its worse with lower...

Fosi Audio recently sent me a fairly new product to try out, their N3 bluetooth receiver/headphone amp. It's a bit of a niche product but I was interested to review one after seeing the photos. It is currently available on "that auction site" for $60, but I don't see it yet on Fosi's main...

This is NOT a review, but an overview of the Aoshida A6 amplifier DISCLAIMER I know that many on ASR completely denigrate tube products, especially the very cheap ones with more aesthetic than functional purposes, as in this case, but considering the probable intended use of an amplifier in...

Hello, I recently bought an ART DJPRE II to replace my modded Fosi Audio X2 because it distorted at higher levels than the normal 39 dB. The problem is I can't really tell which one is really better, it seems to me that the Fosi is kinda brighter or as more resolution and the DJPRE II is darker...
