Same way. It's an opamp too.
Certainly. Like I said, you'd really only want to use it with very high sensitivity speakers so that you can get away with just a handfull of watts.
+/-24 volt rails and a 24 ohm resistor from output to the negative supply will give you about an amp to work with and the device will dissipate about 24 watts.
Bottom line you really want to keep it running single-ended all the time. Going from single-ended class A to compliemntary class B is rather ugly.
Obviously this is academic as long as I keep the Magnepans.
Absolutely.

Konnichiwa,
It's the same one that has been going around for ages and originated with me, used Panasonic FC for PSU , RC55 for resistors and Epcos (formerly Siemens) 4.7uF stacked film capacitors for input DC blocking and PSU bypassing on the chip....
Schottky diodes rectifination and some surplus 500VA+ mains transfomers, still like my SE & PP Valve Amp's better, but that little chip gizmo punches well above it's weightclass.

I think amp topology may also say something about the person's ideals of music... which is why topology is useless to argue about in the end. Kinda like trying to cure the symptom and not the cause?
People who are hardcore about chip amps obviously percieve reproduced music differently than those who are hardcore about discrete designs. Or maybe they are just passionate about different things..? hmm..
My opinion is that Kimura San did have balls for taking something that was already there and just prettying it up with some mystique and jacking up the price. But no more or less balls than the guys who buy some pretty looking wire, put expensive terminations on them, give them cool names and sell them with a 1000% markup..
I personally don't look up to him that much because i was listening to a (much much cheaper) commercial chip amp a few years before gaincard hit the crowd. But that's just me. Still... he's DEFINETLY laughing!
