Customer Reviews
As a pre-Amp, it works with my NAD 302 (as a power Amp) and my B&W DM 302 speakers very well. As of warmer sound, it is really helpful but not very much- just a little bit. Anyway, it is good enough for its price and I am satisfied with it.
From day one, it has a cold solder on the LED under the lamp. I unfold and reassemble, the ice works for a couple of hours and turns off again. Contacted Fosi by email, they offered to send me a new diode and replace it myself....
Other than this, the X3 plays great.

Great product!
My only issue was solved by the amazing support staff, works like a charm and sounds great!
I like it but I'm going to have to play with it to find the optimum set up through my amp
