Hi Vishal!!
I stumbled across your system again in one of my late-night surfing epsiodes - and I am still awestruck by the beauty of those speakers - wow!
I have a friend (audio salesman) who has some Klipschorns that he got directly from the factory way back in the late 70s. They are made from Zebrawood and have a blonde streak reminsicent of your speakers - absolutely stunning.
You mentioned that you might like to try tube amplification. If so, you may want to consider auditioning the Butler tube/MOSFET hybrid amps. I recently purchased one for my system and the sonic improvement was remarkable. Soaring highs, sweet mids, and thunderous bass were achieved. The Gallo speakers really "like" the tube sound, and I'm thinking your speakers might respond well to one of them, too.
Take a look, these amps are really special:

Butler offers an in-home trial period, and I also see them once in a while here on Audiogon. In fact, that's how I got mine. Boy am I glad I made that move!
