Hi @Kevin_Smith,
I upgraded to the H390 from an H190 a few months ago. Could not be happier with this amp. It really is a significant step up from the H190 and just provides fantastic sound no matter the type of music you feed it. Obviously it has a lot more power, but there is more clarity and depth to the sound, and the grip on the bass is really exceptional. I’m using it with Dynaudio Contour 30s, which really need a lot of power to wake them up properly and the H390 gets the best out of these great speakers. It does have a very good DAC, but I’m feeding it via XLR from a Lumin T2 so, although I’m not using the DAC, I can certainly vouch for its excellent SQ.
In my view, the H390 is an outstanding piece of kit that represents fantastic value for money, and I firmly believe you would have to spend significantly more $$ to improve upon it.
