As others have indicated, you can use almost any amp to power a K-horn. The classic audiophile pairing is either a 300b, 2A3 or (if you are more adventurous) a 645 SET amp. Personally, I prefer EL84 but different strokes.
I would suggest that you look at the little Almarro A205A and the Decware Zen Triode amplifiers. Both are excellent and highly recommended. The Decware amp is also made in the good ol' U.S.A.
Another way to go would be the First Watt F3. It's a SS JFET amp, 15W at 8 ohms. The K-horn can demonstrate flabby bass w/ some tubes (300b). This little amp will provide deep, taut bass that the speaker is capable of but seldom delivers. A friend of mine uses this setup in his den, and it's probably the best sounding pair of Klipsch speakers I have ever heard.
