Yeah the sound stage was awesome when in the shop but not so much on my little amp. I do not have a power amp yet but looking at second hand rotel/nad and possibly a new emotiva xpa2 or 3. Pretty much all features i want from the above 3 amps have the features i want its really down to the room calibration. From what i have been reading it is well worth the money.
Input wise i am using 5 hdmi at the moment but would like at least another 1
