What is the most powerful SET tube amplifier?

The Bel Canto SET40 is 37 wpc with the 845 output tube.Thought it would meet my needs power wise with that amount of grunt but it didn't so I need to flip it.My sepakers are 93 db sensitive but maybe they have an impedance dip or maybe I just need to clean the wax outta my ears.I was supprised though.

So Chazzbo whould you still stay with SET or something more efficient?

Dweller may be thinking of the CD-1610 that is rated for 55W per channel. That's the one JA from Stereophile ranted about as only being able t output 9W at 3% THD.

Yes 55 watts is correct for the Cary. Issue 15 of HI-FI+ (English magazine) shows another design using the same tube which is rated at 100 watts made by the "Metropolis" company. Sorry...
