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.
