Class-D amps

Hear Here said:
I have no interest in "gobs of power" amps with my Avantgarde speakers, but I do use Class D amplification.

After testing about a dozen amps of all flavours (after deciding to move away from tubes) I concluded I didn't like Diavelet, Red Wine or Lyngdorf's Class D efforts and I found Sugden and Accupase Class A's a bit on the soft / warm side, but I did like NAD M32's Direct Digital sound. I'm hoping their new Puriti M33 may be even better.

Also rejected for one reaon or another - GamuT D200 Mk III, Micromega M100, Quad Platinum, Sanders Magtech and others. NAD shouldn't be ignored just because it's relatively low priced and includes a DAC - plus streamer and Dirac RC on the M33.

Man, as A.Wayne would say, you need some toooooooobs with those!

My faves with AG:

VAC
VIVA
Luxman MQ300

For solid state:
SIT-3
Luxman 590
Constellation
Boulder

Tubes - no thanks. I'm sure those amps are all great with AGs (you're an expert), but decided I'd listen to MUCH more music with SS powering my speakers. Dead right - has worked out that way, so I won't be going back to the hassle, life expectancy worries, etc of lovely sounding SETs in a hurry.

I'm now CONSIDERING a switcher so I can switch from my NAD amp to perhaps an Art Audio PX-25 SET for occasional listening without having to change speaker cables.

Have you actually tried a NAD M32 with Avantgarde? I suspect not from your reaction. I've used Graaf GM20 OTL, Unison Research SMT 845, Audio Note (with 300B), Art Audio Carissa (845), Art Audio PX-25 and Consonance Cyber 845 monos, but I really don't want to go back as the NAD is so good - surprisingly so!

No, the only NAD I own is the M17 v2.

If you can ever score a SIT-3 (and the necessary resistors), you will be stunned.

I'll try to arrange a demo of the SIT-3 amp, though not sure there are any UK dealers. Looking at the Owner's Manual, it seems to have no way of turning it off short of using the back panel switch. I wouldn't want an inefficient Class A amp that doesen't either turn itself off after a period with no input (an EU requirement) or can be turned off via trigger from preamp.

Has it either of these fetures to make it envirnmentally acceptable? In fact, I'd be very reluctant to consider an amp that burns so much energy that the case gets to 50 deg C when switched on. That's one of my reasons for moving away from tubes! Thanks. Peter

It doesn’t draw much power.
