Fosi Audio P4 Mini Preamplifier

Great pre amplifier

Small foot print was easy to use and give exceptional hi fi sound, I was stunned to hear how loud and clear the music is. I will definitely recommend this pre amplifier

Good not great

Serves the purpose for me as a source for multiple inputs. I would buy again but there is room for improvement. The volume control with the remote can be touchy and there seems to be a slight sound degradation when installed between the zd3 and amplifier. I love that i can control the zd3 with the p4 remote

Creating a better sound

I added this to my already class D amp and the warmth and sound quality is amazing. Plus I now have a remote for my system and the ability to easily change inputs.
