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

Coincident Technology Dynamo 34SE MKII.Would be a seamless match and well within your price range.Read the reviews.

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overpaid for at the recommendation of her child's piano teacher, an old school shrew of a woman teaching ancient and outdated theory with an affiliation to a piano store, lol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.
