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

Grannyring,
I am 100% sure it will sound different. Every single thing you do changes the sound including jacks, wire, solder, chassis vibrations, etc. But, yes, they are using the exact same modules (except that Rouge is using mono modules and Legacy is using one half of a stereo module (exactly the same thing). Yes, you can see pics of the inside of the Legacy amp that verify this fact. Legacy are not doing anything to the modules....they do not touch them......it is quite clear from the pics. They do have a separate ground wire running from each module and they do scrap away the anodizing where they ground (standard practices). Basically, they are stock IceEdge modules in a box.....same as Rouge Audio. What I am 100 % sure of is that with my mods either amp will sound way, way better.....but still slightly different from each other.

Pic #11 shows the best interior shot. Click on the pic again to make it larger.....you can clearly see the amp channel on the top of each module is not hooked up in any way.  Totally stock stereo modules using just one channel for more power and better separation (same as using mono modules).

George,
Wrong, many class D amps are fine with 2 ohms (stable and otherwise) and one of my customers is driving 2.4 ohm Thiel 3.7s ......Fremer drove his 1.4 ohm Wilson Alexx with the IceEdge module without a hitch. Time to tell the truth, dude! Yes, some class D amps are not designed with big enough power supplies to drive 2 ohms or less. After all, how many speakers go down to 2 ohms or less.....mostly the big expensive ones that only the 1% can afford and with 97+db speakers like the incredible sounding Lii Audio drivers.....those big expensive boxes are now boat anchors.

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

Cheers George

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