Wonderful amp!
Finally home after some years in the modeling world (Axe, Line6...).
The responsiveness from a tube amp is about 1000 times faster than a solid state circuit - it doesn't matter if a digital copy can sound or behave like a tube amp, when comes to higher volumes - you can feel the difference.The Mark 3 shows superb quality in all 6 channels from crystal clear clean to heavy overdriven sound. Compared the clean channel 1with my Mesa Lonestar - no difference.
The product presentation from H&K is very good and gives a fair presentation of the sounds and functions. But - they should not add other instruments to the Amp presentation.
3x2 tubes of all kinds gives many options.
Drawbacks:
-Difficult to cut high frequencies in the overdrive channels - could be of value with a built in EQ before the power stage. I solve it easy with a stomp box EQ in the preamp out slot.
-Impression of not so "bullet proof" quality as Mesa. 15 tubes to brake...
-Settings difficult to see , metal knobs should be marked with spots /LED or something.
-Price, of course.
