Tube Watts vs. Solid State Watts - Any credence?

"And also that amplifiers from different manufacturers using the same class D module will often have considerably different max power specs. "

I know that often different manufacturers interested in optimizing performance use customized power supply circuits to that end. Bel Canto with their M series amps is an example. Accountings I have read support the notion that the power supply used makes a big difference in class D amp performance as well, but given the nature of Class D switching technology, these can be much smaller and lighter than what is required to power comparable Class A or A/B.

I have also read of some high end Class D amp vendors using more traditional larger and heavier power supplies with their Class D amps to help assure the nth degree of performance I would assume.

Have a nice Day, Andrew.

Gee, in all this time on this thread no one has bothered to mention the most distinguishing feature of tube amps vs solid state amps. That is the lack of the irritating harmonics present in solid state amps. Not to mention the more natural and realistic presentation. So, in that sense tube Watts are actually even better than solid state Watts than if we only consider dynamic headroom.

Well, I learned something new about dynamic headroom and why it often is not a good thing when advertised even though it sounds like it is. These guys are trickier than big tobacco even!!!

Czarivey, yeah, I guess you're right. it's really the Americans who have been brainwashed. ;-)
