Tubes/SS Power Amps?

Generally speaking class D amplifier modules are less expensive. I have a 100 watt/channel module that cost $25 each in low quantities. It is the size of a pack of cigarettes, including heatsink, input/output connections and power supply connections. All you add is the power supply and the box.

Yet what I see in the marketplace are amps that cost nearly as much as their traditional SS brethren. Its pretty apparent to me that the main push for class D is that you can make a lot more money selling them.

I've been looking at methods of incorporating more tubes into the process. There is even a method of using a power tube for output switching.... the problem with using them though is you can see through your hands when the amp is on.

Atmasphere,
Can you elaborate on your comment of "the problem with using them though is you can see through yourhands when the amp is on"? I'm not quite grasping the meaning, sounds like engineer slang for transparent but I'm not sure.

Thanks,

It was a joke. If you run a real high voltage on tubes they can emit X-rays.

Atmasphere,

Ah, very good and funny, too.

Thanks,
Tim

Prop I would have tended to agree with tubes for the Pre until the unveiling of Coda's new 7X. Its use of very high end double gated FETs with high impedance are very tube like.
Then add their new 7E virtual battery power supply do at the end of 2013.
I have ran a 15.0 for ten months and it barely gets warm even after twelve hours of use.
Codas are like Maytags! lol
