Amp suggestions Klipsch Quartets

I'll preface this by stating that I know that a lot of folks are not Klipsch fans. I get that and the system I'll build around these Quartets isn't going to be a main system. For several reasons selling them isn't an option. My dad bought them back in the early 90s. We're from Arkansas and Klipsch was king due to the "heritage" models being made down the road in Hope. He's been driving them using a Denon integrated from that era. I grew up listening to them, especially on Sunday mornings as he's wake me up to "Under the Double Eagle" at maddening levels. They have sentimental value at a minimum, a certain old school cool factor to boot, and, well, he's gonna let me have them and mess around with them. Although I listen to hi-res digital at work, I'm an analog guy to the core and this will be an all-analog system; listening will be mainly classic rock, folk, jazz, blues, and some orchestral albums. I'm looking for amplification suggestions for the Quartets, knowing that they are some of the most sensitive out there and don't need much push. Tube is preferable but SS is not out of the question and I'm not looking to spend big bucks (under $1000 preferable). Thanks.
