Fosi Audio Q4 Desktop DAC Headphone Amplifier

Q4 DAC setup works great

Very pleased with sound quality I am using the Q4 DAC as a pre amp with a Bt20 pro as the power amp, connected to a set of JBL control 1 Pros and a Cambridge audio Sirrroco Sub woofer, they all work great together even Deepseek agreed it was a great match, I mostly play music via the Optical link to my Samsung 50 inch TV. HIGHLY recommend it Fosi products they have brought my music listening to life again. I created this setup as an alternative to a streaming amp which are usually to expensive. I am looking forward to hearing about the Fosi S3, but will probably be out of my price range, as apart from the Q4 all the other components where purchased preowned. Thanks again to the Fosi team.

I followed the instructions, and the Q4 DAC Amplifier works like a charm. Good equipment, and excellent customer care
