Class D Technology

you have to use a low pass filter and some think the attendant problems with that cause SQ issues

you also have a lot more EMF generated

and more...

Class A maps work relly well in the arctic where you can use them to heat your igloo

I have no dog in this fight since I use a Sunfire

The day will come when Class D will compete and very well be better than any linear amps tube,s/s, class A, AB or whatever, BUT!!

 Class D needs much higher switching frequency (needs to be at least 5 x higher) technology isn't there yet but in the future it will come, only then will ClassD become a contender. Till then good for budget hifi and subwoofer/bass amps.

Technics has progress the Class D race and developed 2 x the present switching frequency with their own made components, in this amp but it’s very expensive $20-30k

When the switching frequency is 3mhz or better, then it can be called hi-end, and will own it myself, then my linear heavy boat anchors will be sold or become door stops.

I have only listened to a couple of brands of Class D amps and was totally unimpressed. That pretty much steered me away from them but I'm sure there are some good ones out there. I'll stick with my Class A thank you.

As Mapman said you have to listen to them and decide. Some people are very pleased with certain class D amplifiers. Thus far in my experience a high quality class AB and definitely class A are better sounding. I’m with George on this one. This could change in the future with further class D development, so time will tell. For some listeners such as Mapman the future has arrived and I can appreciate that per their perspective,  truly an individual call.

I'm not going to list them all, but I've owned quite a few. I stopped with the almighty NCore amps. They almost always sound impressive at first listen, clean, quiet, and cool running. For me though, they begin to show their true sound after a month or so. I've given up on them.

About six months ago I was given an old Hafler P225 which I rebuilt with parts from Musical Concepts. The warm, inviting sound has yet to disappoint. Am I hearing "audiophile" sound? Don't know and don't care.
