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!

As I mentioned before I have a Primare I32 and a Topping TP30 mk2 that I connect to the tape out to drive a Stax headphone system. I have a pair of old BA T-830s connected to the Stax adaptor for the hell of it. Sometimes, when I want the best sound from the Stax, I connect them directly to the Primare, which I did tonight.
After a while I reconnected my 'big' speakers, Canton Ergos, to the Primare and popped I Robot SACD into the BDP-95. It sounded really good. I got to a loud passage and turned the volume down with the remote. Still too loud, so I turned it down some more. And more, and..
I finally put my glasses on and saw that the Primare was down to 0 volume and I'd left the TP30 on. I had been listening to the BA T-830s being driven by a 10 Watt (generous) class T amp the size of a sandwich in a 38'x28' room with the volume less than half way up and it was still too loud!

Picked up a Calyx class d integrated over the weekend. Have to say I'm pretty impressed. Like it way better than the Rogue Sphinx I had for a short while. Lots of power, very smooth, good body to strings and voices, quiet as a mouse.

One really interesting thing about the Technics however is the heavy DSP processing they rely on to flatten the electrical amplitude and phase response. I'm tempted to do this with a miniDSP to see if I hear any benefits.
I have been using a miniDSP nanoDIGI (stereo digital in, quad stereo digital out) to equalize and bi-amp / tri-amp.  Its very flexible.  Using it I was finally able to tame the wild bass modes in my listening room.  Get one, you won't regret it :-)
