Class-D or switching amps, any opinions on??

Probably not the only person here who has owned class A, A/B, D and tubes. Currently using two PS Audio Trio C-100 in full balabnced bi-amp configuration. The C-100s use the same ICE module as Bel Canto, Cary, Rotel and probably many other makers use. To my ears they are exceptional for the money.
I won't say they beat the others in every category. But for many reasons, including the low power requirements and small size, I'll stick with them. When the newer ICE versions hit the used market I'll probably move up in power, although in my small system, 100 watts bi-amped is probably sufficient.
As stated earlier, your ears are what matters. At used prices though, if you are really curios, give one a try.

I meant to say I'm using the PS Audio Trio A-100 amps, not C-100.
Wouldn't an edit function be nice here?

Tim,
not to split hairs, but add PS Audio to your list of ICE users.
Have never owned tubes, for 3 main reasons. Panels, heat and Tubes.

Sam, repeat after me 'Class d is NOT digital'. repeat as necessary. read links I provided in earlier post.

Timrhu - when you move up in power the bandwidth gets lower. Your PS Audio amp's module has higher (65kHz) bandwidth than more powerful 1000ASP 1kW module. It is simply because stronger Mosfets are slower. New much faster Mosfets are introduced every year and bandwidth eventually will increase.

Actually, most or all of the TACT products Sam referred to accept digital inputs, and provide a d/a conversion function in conjunction with a Class D power amplification function. So I think that would legitimize the fact that Tact headlines them as "digital power amplifiers."

Unfortunately, though, that probably contributes to the widespread misconception that "Class D amp" = "digital amp," which it certainly does not in the case of a more conventional Class D amplifier that has only analog inputs.
