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?

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.  

FACT!!!!
No way can ANY Class-D compete with doubling of wattage into impedances 8 > 4 > 2 and 1ohm (current ability) like BJT amps Gryphon Antillion, bigger Krell, D’Agostino Boulder, etc etc etc can

Class-D "may" not blow up, because of severe current limiting at 2 and 1ohm but they can’t drive into those low impedances like those BJT above amps can.
Anyone who says they can is just shilling for sales.

A friend Edgar Kramer, editor/owner of Soundsatge Australia has the Wilson Alexia MkII, and no Class-D he’s tried and reviewed and I’ve heard at his house has sounded any where near as good on them, as his Gryphon Antilion does, especially in the bass where those Alexia’s are 0.9ohm loading.
I will also say the Technics SE-R1 which I rave about is also in that same situation, as GaN Fet like Mosfets output stages can’t do current like BJT’s can into low impedances, 1 or 2ohms

A lot of scintilla owners went from the big krell amps to the H2O and said it was way better.
The Merrill amps double power to 2 ohms.....who cares? about one ohm except for those that have overpriced big speakers that only the 1% can afford?  You really need to try the Lii drivers on an open baffle.  You can use 10 watts and play way over 100db.  Those Wilson's etc. are boat anchors.  You buy a $100K speaker and you have to buy a $40K amplifier to run them....crazy.  A pair of 99db Lii 10 inch full range drivers are $1300 a pair delivered.  Make an open baffle with wings and you have flat to 40hz bass.....and then in a few months (after you have picked your jaw off the floor) you add a supertweeter....then later add some woofs....and you have better sound than a Wilson big heavy boat anchor.
