Oh how I wish Class D amps ...

I sure wish manufacturers and designers would move forward as quickly as is possible on improving the current status of Class D amps ... I have heard them all, some in my own system, and they have SO mcu promise !!! Unfortunately they just do not have it down yet. They still sound dry, unmusical, and strange in the treble ... kind of chalky and rolled off, and definitely lacking air.
I long for the day I can get rid of my hundred pound Class AB monster amp, for a nice small cool running amp that sounds just as good. I am worried though that designers and manufacturers have accepted the " It sounds good enough" opinion, and that the B&O Ice power may be a long time before it is "fixed"... sigh.
Just my rant ...

Thanks Rhljazz ... I actually had the WFS 1000 in my system for a month, and it was a good sounding amp, but not even close to what my mcCormack offers.

I really, really want to go digital, badly ... I just do not want to go backwards in sound quality. My thread is not trolling, or trying to stir up any trouble. I just wanted to see what others feel about my thoughts and impressions. Thank you for your thoughts !

You can overcome the size/weight problem by switching to high efficiency speakers and using smaller A or A/B amplifiers. It is the need for enormous horsepower that requires you to own massive amplification.
There are some pretty great 30 watt SS amps out there that are not too large or massive.

I can't switch speakers, as I have NO doubts it would be a downgrade, regardless the price or brand. Owning a pair of Vapor Cirrus is the ultimate experience ;-)

Well, I have Rowland 102 class D amp that "sound dry, unmusical, and strange in the treble ... kind of chalky and rolled off, and definitely lacking air" and unmodified Benchmark DAC1 that according to another review suppose to "sound lo-fi and shrill". In addition I listen to CDs that again according to opinion expressed on this forum "I found almost all cds way to harsh and shrill sounding" and overall sound is short of amazing. Keep going guys - you helped me a lot!

" 'd' amps have a pretty good phase shift in the HF range due to the Zobel."

To the best of my knowledge no class D amplifier on Earth uses Zobel "filters". With Zobel, you would need to build up your amplifier individually to satisfy requirment of each individual speaker not to metion its other problem. It would be terrible creature....

All, with no exception, class D amplifiers have a challange in HF signal processing. Similar to that of traditional tube amplifiers in LF area and traditional transistor amplifiers in midrange.
