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!

Choice of Dual Mono Stereo or Mono Block chassis 
these are what i use in the UK driving my soundlabs they sound amazing prices start around  600gbp up to 1700gbp for the top reference monos which are what i use
i have heard nothing like them , very detailed , dynamic , powerful but so musical and natural sounding , i have tried half a dozen class D before these , no amp i have heard betters the nord
they ship all over the world

Do you compare to Bel Canto Ref600 also ???

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 :-)

Hi Doctor_lipp!

Yeah, I use it on my subwoofer along with bass traps and other room panels. It is essential for the last two octaves.

That’s not what’s being done here. DSP is used entirely for electrical phase and amplitude. The actual speaker/room response is not considered. Quite a heavy handed approach to making an amp perform like an ideal voltage source.

Still, proof is in the listening.

Best,

E
