Which Speaker System ?

Well I haven't heard that particular Klipsch but, and please don't take offense, if you're only after saving bucks, you shouldn't be looking at Wilson, especially for home theater. The Watch center channel, along with matching stand, that matches the Sophia 2 retailed for over $8,000.00 and the rear speakers are $5,000.00. And that's only a 5.1 system. To go 7.1 or 11.1, you do the math. You can find them used but a Watch 2 with stand is gonna set your back the same price as the Klipsch, and that's just the center channel! The matching rears very rarely come on here used, so they are hard to find. Also, Klipsch and Wilson are two very different brands and have very different house sounds. I recommend you audition both and see what you like better. If it is the Wilson, be prepared to make a big investment, even used. Good luck to you!

Decision made; purchased the Klipsch Palladium P37 system.  Now, I need a really good pre/amp or receiver setup to match the Palladium's and get the best performance from those horns.  

Does a really good tubed unit exist for home theater???

What kind of a setup are you looking to have, 5.1, 7.1, Atmos, etc?

Do you plan on running multiple subwoofers?

Pre-pro/amp compo, AVR, AVR/amp combo?

Budget?

Either 5.1 or 7.1, not sure yet.  I will have two subs.  I need a front end and amps that will work well with the Palladiums.

ARC did make a multichannel preamp, but I believe it is long gone. The remaining reasonably available high-end preamp is the Parasound Halo P7 with 2 7.1 inputs.

A lot of high end 2-channel preamps have "bypass" mode though, which let's you use an external source as the volume for movie watching, and returns to normal operatoin for music.  With something like an Oppo with built in volume and analog outputs that's an easy integration.

Personally I use the P7 for everything. It comes well reviewed. Certainly a step up from the P5. :)
