I have one Class A amp and have had two variations of Class D amps. The Class A amp is significantly smoother than the Ice Powered Class D amp, but the Class D amp with Ice power modules blows it out of the water in terms of raw dynamic power, but it tended to be harsh on the upper end frequencies where the Class A amp shined.
Now lets talk about the other Class D mono blocks I have which do not use Ice Power devices, they use proprietary design output sections which are liquid cooled. These are the Anthem M1 Class D mono blocks. These two amps absolutely kill the Ice Powered Class D amp and kill squared the Class A amp. The Anthem M1's are smoother, cleaner, more accurate and balanced than the Class A amp. They also have massive output power which is so dynamic that you will hear things that you never heard before. I'd suggest that you find a pair of these, as they run barely warm to the feel in the middle of summer and consume only 3 watts in standby but under use will deliver 2000 watts per channel at 4 ohms with virtually no distortion. The only issue will be the cost, these are $7K per pair, therefore well outside of your budget. But the point is, if you are ever looking to have your cake and eat it too, it is there.
