What amplifiers/integrateds do you like with Cornwall IVs?

Lots of outstanding SET amps out there, but some HE loudspeakers require more drive. I'm no engineer (maybe someone else with better chops could explain), but it seems like a big impedance swing across the spectrum can tax many flea-watt amplifiers making the system sound anemic.

@boothroyd -That's the beauty. Small tube amps for solo cello and Class-A solid state for 'Zeppelin. The Cornwall can handle them all.

Lots of great points to unpack. 

First up, the Jadis issue.  That is something.  I'm glad to hear that there may be a pair running under one.  I am 46 and never thought I'd own a Klipsch speaker.  I built an Elekit 300B and did many high end upgrades.  I like how the Klipsch Heritage Series sounds with well made tube amps. 

@jjss49 , I think you are probably right on the mark. There are others who are great and smaller who are more than deserved to be on your list above. I would open for question whether Cary is as good as the others but I must admit that's perception--not reality. I haven't heard their product in 12 years. 

@boothroyd, Yes. Exactly.  I love SET and how its topology sounds at certain levels but it is not enough watts even in many high efficiency setups.  I think 25-30 watts is ideal.

Boothroyd, tell us more about what you know on that Jadis combo. 

"...I'm wondering if KT150s are too much, and I should swap in EL34s or variants..."

A 25-50 watt EL-34 amp will give you everything the Cornwalls  have.
