Seeking Tube Integr. Advice for klipsch forte

My brother is ready to take the plunge into tube gear and is looking for some helpful suggestions. He wants to get an integrated tube amp, preferably something self-biasing with his price range being anywhere from $600 to $1,300.

Being fond of his Klipsch Fortes, he is planning to keep them for some time to come. Their sensitivity rating is 99 so of course they should be very easy to drive. But how much power will he need to retain the tight bass response he is used to from S.S. gear while at the same time achieve the gorgeous mid range bliss he wants?

He is aware of the Primaluna but right now it's his only idea. I suggested he might get great bang for his buck with something in the 12 to 30 watt power range and not have to spend as much as he thought. We decided to ask the tube-lovers here at Audiogon for their advice. We would much appreciate your input.

BTW, His musical taste go from piano jazz all the way to the Grateful Dead. Probably with less emphasis on rock and more on acoustical vocals and instrumentals with time.
