Class D amps seem poised to take over. Then what?

I am certainly biased by my lifetime final amp being a Class D. But I know that after 30+ years of development, Class D seems to be on a high plain. I know there are now many, many companies focusing on Class D and, maybe, a good handful already as good as it gets. My Class D amp is as smooth and beautifully musical as a great tube amp and as punchy and detailed as a great SS amp. I am satisfied and done with my search. A class D amp has effectively taken me off the amp merry-go-round. It’s about time after 50 years. And, for me, this Class D is a milestone. Will all other classes of amps fade away?

Class D amps can sound good, you just have to put a tube dac and tube preamp in front of them.

yes, but is Class D stable into 2 ohms?


Yes, they are stable into 1ohm, the H20 amp that Henry used to make was used with the apogee scintilla.

A lot of scintilla owners went from the big krell amps to the H2O and said it was way better.

No amplifier can double it's wattage when impedence is halved.

These companies that claim double wattage when impedence is halved don't give the actual 8ohm measurement, which is usually a lot higher wattage than their spec sheet has listed.

I don't think there is an amp made that can direct drive the apogee full range, the midrange when direct driven is .14 ohms

Even the big high bias amps built with BJT's can't do it. When stereophile measures them their 8ohm full power measurements are a lot higher than the spec.

Man alive...
The more time i spend here the more it feels like a bunch of geezers trying to hang onto the old tech and talk about how $5k cables augment sound.

What do you think satellite TV comes from vacuum tubes. Satellites use vacuum tubes.

If you combine a DHT preamp and a transparent SS amp you are most of the way towards a very good tube like sound. 


I've never owned a DHT tube preamp, but with the octal preamp and solid state amp I'm using now I tend to agree.
