I just visited the Highend in Munich and had the chance to listen to two of those monster SETs.

Sure, whatever you heard at the show is not the definition of sound of whole topology but the entire question is very interesting: is anything fundamentally wrong or fundamentally advantageous in high power SETs. The question is very interesting and I did not hear any credible chatter about it.

Surely if we have a tube with 10W plate dissipation and 200W plate dissipation then the difference would be in size of plate and in voltage and current that would be applied to plate.  Certainly it will not be it. It will be zillion of other moments of the tube construction not to mention the very different amps the use those very different tubes. I would not even mention the fact that 1W SET and 60W SET would drive very different speakers. It is like you bring to me now a GM70 amp with 45W then what would I do with it? I mean a higher power imply a completely different topology of loudspeakers. Even if we use high poser SET juts for bass then we immediately dive into DSET topology with very different rules of the game.

So, I think it is very difficult, if aver possible to equate the generals cones or pros for high power and low power SETs. I have see people who build/sell high power advocated some point and some claims that high power has some benefits. I have seen some low power people did the same. Why I said that there was no chatter then? Because I did not like arguments of neither camp and I did not find their points of view credible.

I still have no view about high power vs. low power SETs. I know that I have bias against high power SETs in case they use high voltages but it is about it… Unfortunatelyall amps that have a lot of dissipation on anode use high voltages…
