What amplifiers/integrateds do you like with Cornwall IVs?

I understand a Jadis DA80S will bring down the house with the Cornwall IV. Jadis has a pair in France and A/V Therapy in NH mentioned the combo was positively stunning.

i am not a klipsch guy but i would think best of single ended/triode amps from:

decware
linear tube audio
wavelength
cary
audion
air tight
audio note

would fill the bill... at least that is where i would head if i had a 100 db efficient speaker i liked...

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.
