verdict on class D amps?

I think the technology has improved quite a bit. But it still varies from manufacturer to manufacturer. I had attended a demonstration about 18 months ago at the local dealer with both VTL and NuForce driving a pair of USHER BE-20s. The VTL was hooked up to the speakers first, and they sounded phenomenal. NuForce's reference monoblocks were then put to the task after the break, and I got to sit in the sweet spot. My personal take was that the NuForce exhibited a lot of the undesirable characteristics that everyone had been complaining about digital amps. (At least to my ears)

Moving forward 12 months to RMAF 2008 in Denver. There were a good amount of manufacturers showing off their digital amps. Some still exhibited those undesirable characteristics, but some sounded very promising. One that stood out the most, for me, was Wyred4Sound. I would love to have the opportunity to bring one of their amps home to compare to my Pass X350.5 side by side.

But I think it is safe to say that digital amps, in general, are moving towards the right, and a very promising, direction.

Frank, you hit the nail on the head on class D amps. . . which are not digital devices btw. . . They are evolving rapidly, but like with amps based on any other technology, they vary in sound by model and by manufacturer. . . always have, and always will. Guido

Guido - that is an important distinction. Many people object to principle alone (switching) not understanding that time can be as analog as frequency or voltage. They probably already have CD players or DACs with delta-sigma D/A converters, SACD players or DSD recordings - all of them class D like (PWM).

Frank do you know if the Nuforce amps were well broke in? They need at least 200 plus hrs for a reasonable break in. Which model was it? I respect your feelings and thoughts. Ive had all versions of the ref 9 series through upgrades. By far the latest V2 technology is the best version. Like i posted above if you are happy with your system good deal.

thanks for all the info!!! I unfortunantly do not know of a local shop who carries any class D stuff.... thus I can only go by what I read on these forums & also on the manufacturers websites.

Can someone list a few different manufacturers of class D/T amps that I should consider?

The only manufacturer website that I have read about is the Seymour Ice stuff
