The Truth about Modern Class D

All my amps right now are Class D. ICEpower in the living room, and NAD D 3020 in the bedroom.

I’ve had several audiophiles come to my home and not one has ever said "Oh, that sounds like Class D."

Having said this, if I could afford them AND had the room, I’d be tempted to switch for a pair of Ayre monoblocks or Conrad Johnson Premiere 12s and very little else.

I’m not religious about Class D. They sound great for me, low power, easy to hide, but if a lot of cash and the need to upgrade ever hits me, I could be persuaded.

The point: Good modern Class D amps just sound like really good amplifiers, with the usual speaker/source matching issues.

You don’t have to go that route, but it’s time we shrugged off the myths and descriptions of Class D that come right out of the 1980’s.

GFi,

put your money where your mouth is and buy the EVS 1200. Then, and only then, would anything you profess, potentially have any value. Alas, you have so convinced yourself that all class D sucks, that you would have to bash it just to save face.

Get a life


To anyone else who has denied themselves the opportunity to hear which of us is telling the truth, it’s your loss.

What more could Ric possibly do than give you a money back guarantee?


I had no way of knowing whether his tweaks would be magical, until/unless I bought it. I did, and I did not return it

$2200 is an absolute bargain in todays world of uber expensive hi end audio amps

Apparently, the GaN Voyager is still going through its development issues. Why? It’s a ground up build, whereas RIc was able to take off the shelf newest IcePower 1200AS2 modules and analyze how they could be improved, and did it. BIG DIFFERENCE


I have owned lots of TOL/SOTA tube equipment, Lector, Musical Reference RM 9, Judd Barber custom OTL amps, Rogue M150s, and lots of SS amps; Parasound A23, NYAL 300 and 600 (yes Im that old), Bell Labs, my favorite being Kinergetics KBA 75 class A, and plenty more that I cannot recall


Additionally, multiple class D amps; PS Audio, W4S, Emerald Physics 100.2 SE monos with upgraded fuses

Ric’s EVS 1200 is the only one that reminds me of the KBA 75

Tweak you started it again, I told you, every time you bring me in by name, I’ll put up the phase shot of the Icepower amp.

Golf, that **** doesn’t worry me, I just hope the mods see it and treat it for what it’s worth. He’s a Nelson Pass basher, we all know it.
Cheers George

George, his post should be removed for crossing the line in offensiveness, and he should be given a warning, if not banned.

Oh wow, for some one who routinely attacks other A’gonners personally you are very very sensitive fellow.

So, lets stick to facts:

You just don’t get it tweak, this is why many find the upper mids/highs objectionable on Class-D, why would I want to listen to an amp with this much phase shift already 25 degrees! at 2khz, and it get’s progressively worse all the way up to 70 degrees!!! at 10khz.

You are completely misreading the data you posted.

As I posted before, the chart you are showing is the phase angle of the output impedance, not of the audio signal. Look at the datasheet for the 250 ASP, which actually shows the phase angle of the audio signal itself.

As I also posted before, most experts agree that phase angle doesn’t mean that much, so even if your horrific misinterpretation of data was accurate (and it is factually wrong) I doubt anyone would hear it.

Some one who had integrity would strive to correct errors of fact when possible, instead of attacking the character and taste of those who disagree with him.  Please, show us your mettle.

Kisses.
