Class D Technology

It is far from mud slinging, buy it appears that you make strong technical statements on the subjects that you are completely unfamiliar with.  I pointed out units just to show that you don't have any electrical engineering education.  This thread is not too bad, but your crusade against Delta-Sigma converters is plain insane.  Cheers.

I understand your just protecting your JR120 investment, that "if" you had the knowledge you could have built for 1/8th of the price. http://www.usaudiomart.com/details/649188442-icepower-200asc-modules/

And I’ll bet you’ll be the first to sell it when the technology comes that get’s rid of the switching noises problems without effecting the amps sound.

It’s about sound George. Obviously from your many condescending posts, you consider yourself the foremost "guru". Try a little humility and you might learn something.

Best to you George,

Can’t "see the forest through the trees" even though they are presented to you.

The Apogee’s in 1ohm mode were never meant to be driven with tube amps, especially ones like you mentioned, they needed big s/s amps like Krells, Classe, Mark Levinson, yes and even the earlier big JR’s, ones that could pump current into most loads down to 1ohm. You should know this being an owner of a Krell FPB-600c and why didn’t you drive the Apogee’s in 1ohm mode with that, I’m sure you would have changed your mind about the classd-.

Only condescending to the posts that believe that Class-D can drive a speaker to "it’s full potential", when most of the load it represents is around 1ohm, and we’re not even mentioning -phase angles yet. Though I think they will be pretty benign being a planer speaker.

Cheers George

Oh, you mean like my Classe’ Audio DR-25, dual bridged-mono DR-9s, or my Krell FPB-600c (6000w/ch@1 ohm with 143 amps of current according to JA’s bench test in Stereophile)?

I had no idea that those would work well with Apogees. Oh, wait, I used the DR-25 and Krell with my Apogees for years before trading for the equally-difficult-to-drive Thiel CS-5i’s.

Best check people’s Virtual System page before spouting off. Where’s yours?
