What amp do use to drive your Klipsch Cornwall I,

What amp, tube or solid state are you using to drive our Klipsch Cornwall I's or II's. I hear allot about 6BQ5/EL34 amps and Horns. Of course the Cornwall need more power than the LaScalla or KHorns. I see allot of people use simple receivers on their Klipsch too. I want to stay with separates so power amp tube or solid state. What are you using with excellent results?
