Which high power SET

Ait, thanks for the detailed response. Wrm's choice of the word "awesome" is an understatement, if anything :-)

I'll add to your comments, relevant to the thread, that the 1.2 ohm output impedance is of course significantly lower than that of more typical SETs. And it is low enough so that the effects on frequency response resulting from the interaction of that output impedance with widely varying speaker impedance are not likely to produce unintended results when used with speakers designed with the expectation they would be used with either push-pull tube amps using feedback or even solid state amps.

And thanks for the invite. I'm not in NJ, but every once in a while I have occasion to visit northern NJ, and I'll keep your invitation in mind.

The first is the size of the listening room and the second is the listening level preference. The impedance curve is important as well, but to me speaker efficiency is a much lower priority.

For me, #1 priority is amp's ability to drive speaker sufficiently. If not, SQ will suffer whether low or high listening levels from my experience.

Listening level is not a factor in my book since I listen to all different levels depending on the situation.

Ait, have measured the bandwidth of these behemoths?

This is an amazingly interesting subject. I really appreciate the responses, technical explainations and detail. Very interesting indeed

Thanks all

Could not agree more.
