Class D is just Dandy!

I thought it was time we had a pro- Class D thread. There's plenty of threads about comparisons, or detractors of Class D.

That's fine, you don't have to like Class D amps, and if you don't please go participate on one of those threads.

For those of us who are very happy and excited about having musical, capable amps that we can afford to keep on 24/7 and don't require large spaces to put them in, this thread is for you.

Please share your experiences with class D amps!

madavid0, the only time that I do not hear mesmerizing music with resolution, staging, imaging, macro and micro dynamics, authority, and amazing listenability with zero fatigue is when my class D Rowland M925 mono amps and the rest of my system are... Turned off.


On the other hand, I believe you have heard these very same type of comments from me and many other music lover on this and other similar audio watering holes before.... And they ain't changing.


This does not imply that my amps, being class D are inherently superior to yoursma.... Just that I love the kind of emotional music that my amps express to me, for my musical taste, with my other components, in my own home, potentially 24/7/52.


Can my musical experience be enhanced further... Sure thing. Next Thursday I will be taking delivery of a Rowland PSU (Power Storage Unit)... An external power supply based on supercapacitor technology that I will apply to my Rowland Aeris DAC. I am excited about third party reports about it this far, and am anxious to try it on my own system.... But, my class D M925 mono amps are not going anywhere *Grins!*

I use bare ICEPower 250 ASP modules. They beat a lot of premier class A amps.

Also, you bring a lot of attitude. Not everyone on this list has mentioned uber pricey class D amps. Some were quite affordable.

If you are looking for a place to start a linear vs. class D argument I really would be happier if you took it elsewhere or started your own thread. As posted, this thread, which is one of the most popular on right now thanks to the readership as well as proponents who are participating is for people who like Class D. :)

Thanks,

E

I've heard it said (by a class D proponent) that ICE sucks, but Iceedge is going to be a game-changer. Truth?

Also, it's widely claimed that class D is improved with linear power supplies -- fact or fiction?

ICEPower went through several incarnations. I can attest that the AS (or ASP if powered) is superb.

ICEedge is the chipset without the amplifier. :) Just the brains. So I think that we’ll start to see a lot more product differentiation among vendors.

The normal ICEPower module is 100% complete and tight in space. There’s no place to modify anything. At best, you can put in your own input buffer stage, and you can do lots with that. Transformers, tubes ets. but the ICEedge is the place where you can go really bonkers with part selection and circuit design.

I have no personal experience with these amps and linear supplies.

Best,

E
