Which class d amp?

You may want to check out http://www.digitalamp.com.

The Cherry and 4800 amps have sounded great in my system during long and short borrowings, respectively. Powering VonSchweikert VR4JRs.

Although my system is not the same as it was when I owned the CIAD200s or borrowed the 100 watt Rotel ICE amp, I feel that the DAC amps sounded better than I remember the other Class Ds sounding.

Gobs of power yet very clean w/out being etched. Complete control top to bottom, soft to loud. Not based on ICE or UcD, they are a proprietary design.

There is a new version of the Cherry coming out but I have not heard it.

(Disclaimer - I'm getting to be friends w/ the owner/designer, so take the above as you will - Won't hurt to check them out though)

Its more about synergy with your components, source through to the speakers. I am driving my VR-4JRs with Bel Canto IcePower monoblocks and they work very well together. It would help if you listed your other pieces.

nice receent reviews of the new series of Bel Canto amps

There are only three class D amp's I've come across yet that I'd consider truly up to par for two channel performance:

H2O Audio Signature 100
Spectron Musician III Mk2
Red Wine Audio Signature 30.2's (or 70.2's)

This is not to say that I have heard it all. There are probably other great products out there, but compared to the Channel Islands, Exodus, NuForce, Jeff Rowland, Bel Canto, etc.. the above three stand out particularly well to these ears.

I have heard, in chrono order over the years:
H2O 250 sig (early model - and it's the only one I haven't actually owned from this list).
Spectron M2
RedWine Sig 30
Nuforce Ref9 V2
Bel Canto S300
PS Audio A100
NHT Power2
Channel Islands D200

All have come and gone (but the H2O as it was never mine). Some lasted less than others, but the max was about 2 months. I'd put the CI D200 at the top. The H2O was good but it was a long time ago and I was less experienced then so I can't say for sure what I think of it.

Oh - I missed one - the Lyngdorf TDAI2200. I still own it (albeit it's been only 3 months) but I have stopped looking for amps, whereas it used to be that I'd be constantly on the prowl for a new amp. This is the most natural-sounding amp (well, it's more than an amp) and I NEVER find it compressing at loud volumes, or missing frequencies at low volumes, or sounding anything but 'just right' all the time. It reveals recordings quite well but not ruthlessly so; it does warm up the sound a *wee* bit. Just enough IMO.

For perspective: Have also owned a variety of budget to mid-level tube amps, mostly integrateds. No can do any more - if I ever went tubes again it would have to be on the high end, where I am given to understand they sound more like very good solid-state although I have not been privileged enough to hear any but the VTL Siegfrieds at a dealer demo once. Very nice but at $40K it better be.
