Default More info. on class t amps for Gavin

I've been doing some research on class t as it's been bugging me, never having heard of it. According to these two links, it is basically what we call class D, which has been around for decades, and is basically a high frequency pulsed output stage which theoretically achieves close to 100% efficiency but there is still the thing that I don't like about it, the difficulty of filtering the high frequency artefacts, and that, plus those from the switch mode power supply will almost certainly add some colouration and it's a well established fact that adding a small amount of distortion can in fact actually enhance the sound perceived by a lot of "audiophiles", hence the resurgence of tube power amplifiers, they add a little second harmonic distortion which gives that "warm" sound.
I notice that the company is no longer in business, no doubt because, other than for portable and auto uses, it could never be a real competitor for modern DC coupled high power ultra low distortion amplifiers with incredible skew rates and damping factors.

Hey all I know is people say they sound amazing, and the smaller kits are great for running off 12v dc. My main interest in them.
Also, if it's good enough for Audio Research to produce an amp based on one of these chips, it must be pretty decent as they've been doing high end audio for a very long time.
