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!

I would also like to hear someone chime in and give thier thoughts on the differences between the ICEpower ASP modules (like what is in my JRDG 501's) and the current crop of NCore modules. I'm really not looking to upgrade, but would like to hear from owners who have had both. Uhm - this may be directed at Guido :)

Not many Jeff Rowland owners have chimed in (Guido, aside). I have the (older, yet updated) 501 Mono's. The ICEpower modules inside have been taken from and early revision to the (presumably) latest (Rev J) as I bought them from Jeff in January (really not sure if its an upgrade - I had a bad power day in December and both blew).

I'm very much thrilled with the sound of the amps - yes, they are detailed, and very natural in the midrange. But what I've noticed (compared with my prior 'very nice' Audire class A/B dual mono) was the noise floor and, beyond my logic, the black backgrounds with LP's. It's like noise supression system on my turntable. I've gone back and forth - and something really magical happens in the treble. I hate that word "magical". I really do. But damn it. I can't explain it.

My next 'upgrade' will be the PC-1 modules. They are sitting in my music room, but I haven't installed them yet. I'm laboring through they very well documented, and necessary, breakin period. For those wondering, it's a bit like 7 stages of grief, with maybe 4 stages. Stage 1 - power on and a euphoric midrange, but not right. Kinda boomy but airy. Stage 2 - lack of midrange but bass rises. Stage 3 - bass is getting inline, and so it midrange. Stage 4 - OK...these are nice....
