I'm unclear on what this is. "Class T" is a marketing BS way of saying class D when you dont want to say class D due to misconceptions bout class D in some audio circles. (bass players and sound guys got over their doubts about class D a long time ago. So you dont see "class T" bass amps or live sound gear. Some audiophiles are still laboring under the delusion that class D means digital though).
The confusing bit is the reference to 'linear power supply support'? Class D/T have PWM power supplies. It's the defining characteristic. Linear and PWM power supplies are mutually exclusive.

CalaverasgrandeThat's not how it works. It's PWM, not PWPS. PWM is pulse width MODULATION. Not pulse width POWER SUPPLY. The PWM is the modulator. Not the power supply. They're two different things. Yes class D is a switching amplifier, and yes many use SMPS (switching mode power supplies), but they can and do also use linear power supplies. Both can be good, and either can be bad. It's all in the implementation. Normally if you buy a class D amp that requires a wall wart, or external power supply. You want to use a SMPS, because linear can cause ripple issues. But when designing your own amp. You can take care of that issue easily enough. So yes this is a linear power supply on a class D amp, but that's not necessarily a great thing. Nor is it a bad thing.

amb3cogSo it's a class D amp run off a linear power supply? I'd love to hear the marketing bs fabricated to justify something so dumb. Except I really wouldn't.
