A perfect fit with an audio-tecnica AT LT60x turntable and a Sonos Five.

After using this little valve pre-amp for a year now I am very impressed by its sound, build quality, and value. The device provides a wonderful warm analog valve sound that is distinctive when compared to the switchable built-in preamp of the Audio-Technica AT LT60x turntable. When plugged directly into the 3.5 in jack of a Sonos Five it creates the perfect budget analog audio setup with digital expansion capability for the future. The usefulness of physical volume and tone controls is a feature I use every day. Sometimes lo-tech is a good thing! Highly recommended.

Fosi Audio Box X4

Unfortunately I sent the the Fosi Audio Box X4 back as a return because I ordered it in error I wanted the new Fosi P3 pre amp,so, I ordered it. Since then I have received the P 3 and have it integrated into the system I have designed. Currently it is not doing very well but ,I am aware of changes/adjustments required to improve the system overall. Don't misunderstand me. I am pleased with my purchase. Adjustments need to be made.
