just to highlight it since its a long read and this point is toward the end.

"guys---the sound quality issue of amps once again raises its ugly head----i ahve no reservations of including class D amps in my amp challenge and have done so in the past---for years dave and i have been strong proponents of class D as it just makes sense---yes it is harder to do class D at higher frequencies but not impossible---its just not as important as we usually reserve most of our power for the lows anyhow----and as for actual efficiencies i have posted such numbers in earlier threads---they are probably in the archives by now but at full power 70 to 85 is typical for class D and 55 to 60 is normal for class a/b-----at one third power (the most important due to the nature of duty cycle of music) the a/b is usually about 25 to 30% and the class d is about 50 to 60 percent........RC "

alpine's new pdx full range amps are also class D, as well as eclipse's "ICEpower" amplifiers, like the xa2000.

That's a VERY nifty amp. I'd like to see more in the future. :)

most of the full range "digital" amps are actually class-T or variations thereof. Not true class D topology.
