Small size, great performance

My latest from Fosi: the Box X5 to amp my Thorens turntable. And man, does it work. Better than expected, I guess. Crisp, clear.

The X5 really is that Fabulous

I’m sure you’ve done your own research and know the hype. I’ve been listening to the X5 for past few days now and I am very impressed.

The separation and detail picked out is just tremendous. My set up is AT-LP120x with VM95E to the Fosi . Then to a Denon amp. The X5 really does punch above its weight.

Excellent!!

Good Preamp

My only experience with preamp was the mani and phono of the Klipsch power speaker. I was impressed with no hiss, no distortion and good sound quality. I have the ortofon 2M red thus first two gain settings required cranking the volume. At 56, no problem with power or sound quality. I like the punch it gave the music and these LPs are 40 years old. I have to give Fosi credit good price and good preamp.

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.
