Very pleased with the Fosi Box X5. Highly recommend it.

I was very surprised with the design and the build quality of the X5. My receiver was struggling with the signal from my turntable. While recording to Minidisc, I had to set recording level to 9 and sometimes 10, so I read about these phono pre-amps and liked the specs of the X5. When it arrived, it was easy to set up. Moving magnet cartridge settings to +48dB and WOW! I was floored. I couldn't believe the improvement in sound quality. The x5 offers amazing dynamic range, clarity and depth. My old records came to life again. I'm very impressed. Not only that, but we can also upgrade the op amp and I have an OPA2134 on the way to increase the warmth. I would highly recommend the X5.

AWESOME!

I have been using the P5 now for about 1 month and couldn't be happier. I feel it is better than my PA555 and as good as my IFi Zen Phono Air. I prefer the size and style of the FOSI, the IFI is unique but doesn't fit my system. The only thing that would be nice to have is a subsonic filter. I can definitely recommend the FOSI P5.
