Capacitor-less amps

I think what he meant is that no caps in the signal path. I think Arcam Diva series do not have caps in the signal path either. They use some kind of servo circuits on the output to remove any DC residual.

But for the power section of the amp, there must be caps there.

wavac amps don't have caps in the signal path.

btw, they sound wonderful.

Just FYI, an amplifier without COUPLING capacitors (ie without capacitors in the signal path) is called direct-coupled. All the direct-coupled amps I know of (but I don't get around much) are solidstate. All tubed amps I'm aware of have at least one coupling cap per channel in the signal path.

Parasound JC-1 monoblocks. They are DC-coupled.

A DC-coupled amp is really a DC power supply with analog command input, and a high slew rate. In fact, many years ago a power supply manufacturer demonstrated his product at a trade show by playing music through it. Subsequently, some audio amp manufacturers took this approach.

I have a couple of old Kenwood L07M amps that are direct coupled, and they do sound really good dispite their age (or should I say "vintage").
