Good enough for this price

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.

Almost satisfied

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.
