"....It sounds very clean, clear and smooth like nice breeze in summer mountain with high resolution.
However mid and bass are thin and light. I recalled the sound of Magnepan.

Digital input from fidata sounds better than analog input, as its resolution and tonality.
In my view it is the best except phono input I didn't listen this time."

More GAN incoming, now from Mytek.

Hmm! interesting, could be a winner. 
They talk about transistor switching (hopefully frequency used) and "very gentle negative feedback" resulting in "silky tops".
But don't give any details of the switching speed, feedback db's or what phase shifts are in the upper audio band "tops"

The thing I don't like to see is it only has 10kohm input impedance, not good for preamps with small value capacitor coupling, passives or most tube preamps, yet they give the choice of two gain setting 23db or 29db latter being good for passives or unity gain preamps.     
Time will tell when one is bench tested.

BTW, think you should start a new thread on this amp, it probably will deserve it.
Some like "Mytek Empire power amps, with GaN based technology."
