Class "D" amp? I do not have a clue. Do you?


I have been a serious audiophile for 30 years and class "D" audio is new to me. Most important, what do they sound like?

I don't know if many here address the electricity going to their gear as much as I do, but what I have found is that the D amps that I own need the best power you can give them to sound their best.

That means the less you do to clean up the power to your amps(and whole system)the worse they will sound.

I recently did some more upgrades(I am firmly in the Shunyata camp)and the improvement to the sound of my system only let the clarity of my D amps(Red Dragaon Leviathans)shine thru.
I was pleased before, but really impressed afterwards.

The Red's will sound nasty if you feed them nasty power and sources, they are revealing, and if other D amps have the same traits, then perhaps those who do nothing to clean their power(dedicated lines, power conditioning,power cords)have heard the nastiness and attribute it to the D amp .Thus a myth about the poor sound of D amps is taken as part and parcel of all D amps in all systems.

It would be interesting to hear from others who own D amps of their stories and findings concerning the power being fed to their amps.

And I am curious if those who have found D amps not to their liking use any type of power conditioning , dedicated lines or upgraded power cords.

My Reds use Shunyata Annaconda Helix into a Hydra 2, ,the hydra 2 is connected to a 20 amp wattgate which is wired at the panel with 10 guage Romex of about 10 feet in total length.
Front end gear is on another 20 amp line, into a Venom plug, then 20 amp Annaconda Helix to the Hydra 8.

As I mentioned, before I went this route I was happy with the sound of my gear/amps.
Now I am very pleased.
I'm convinced the better Class D amps are those that pay special attention to the power source on-board.

Mapman - That would explain better reviews for BC Ref1000mkII
vs. original Ref1000. Same Icepower module (1000ASP) with built-in SMPS but new version has additional supply module/board with bunch of electrolytic capacitors.
That goes both ways when it comes to power. A large improvement was made not only to my Nuforce amps but all else in my system when i invested in power regeneration for my systems power supplys.

Also trying out the latest from Nuforce there Ref 18 and i can say without hesitation King Crimson will not run you out of the room if fact you will want to get comfortable and hear the whole lp. IMO
It is also possible that new generation is just only a little bit better (like BC Ref1000M with extra power supply caps) and "new generation" allows some critics to reevalute (read: save face) since others scored them much higher. For instance REF1000 was evaluated bu Martin Colloms for 10.5 points while Krell got 130 - that's less than 1 of 10. Ref 1000M is Stereophile class A. Sound like two completely different amps but in reality both use exactly same Icepower module with built-in SMPS.
