used Integrated tube amp under $1500 for Klipsch Cornwall III's?

OP said

yes my first used tube amp being of the older variety will look kind of wierd on the piano for the time being

I would much prefer seeing an old tube amp rather than a new one ANYWHERE. Any amp on a piano seems a bit rude to the piano, but, when younger I might have done it, do what you gotta do! Get listening!

btw,

the heat from the bottom any equipment, especially tube equipment can/probably will negatively effect the wood below it, 

that's good to know thank you
it's actually a cheap but stunning looking chinese piece that my girlfriend overpaid for at the recommendation of her child's piano teacher, an old school shrew of a woman teaching ancient and outdated theory with an affiliation to a piano store, lol

My $0.02 worth: look on craigslist or hifishark for a used Harman Kardon A224 Trio integrated amp for approx. $300.  It's an EL84 unit made in the late 50s/early 60s and built like a tank.  Very colorful and snappy.  Have the caps replaces (all of them) for $150 and replace the tubes if necessary (maybe $75) and have a ball.  The most sound for the buck I have heard in these audio price-inflated times.

With Forte IIIs you can use anything from low wattage to whatever...If I didn't already own have a Dennis Had "Inspire Firebottle" single ended amp I'd seriously consider the Coincident Dynamo (nearly did when considering the Had amp, but was charmed by Had himself in a video, and the Firebottle was cheaper as a barely used 12wpc model). With a Schiit Freya this makes a combo that's hard to beat by any integrated...for something in the push-pull tube world I'd look at the new "Black Ice" stuff from re-named Jolida MD, as having owned a 502p amp I can vouch for their quality, and they're still relative bargains compared to other stuff out there.
