Good looking Towers for < $2000?

I'm in the same situation as you. I have been contimplating new tower speakers to replace my studio 20 v5. I truly enjoy the 20s except for the lack of true depth in the low end. I struggle with the idea of adding a sub or going with a larger floorstander. The Rel s2  looks promising or do I go with Paradigms Prestige series. You're not alone in your search!

I was just thinking out loud.  There's no way I'm looking to get a sub.
Don't want one.

Silverline Preludes (not the "Plus" version) have little alloy woofers in a D'Appolito array and the imaging of mini monitors, albeit with useable bass…a screen over the alloy tweeters for "grill off" no worries listening, and sound really friggin' good with a sub or two. The tone appeals to me as it's somewhat neutral, and efficient enough to respond well to a modest (60 watts or so per side) tube amp. I "auditioned" these at a friend's house a few years ago and consequently found a clean used pair online for 400 bucks…love them things, and they sound better with single runs of wire…all good.

Have passed through the hundred hour mark on the Prelude Pluses.  Finally hooked them up to the tube gear I had bought them to use with (78 wpc EL34 mono blocks; 6H30 & EZ80 rectifier pre-amp).  I am no longer thinking I need to get a sub.  Lower mid-range and bass are fuller with these tubes than I expected and actually seem better than with the much higher powered solid state gear I used during the breaking in period.  Go figure.  I think these Preludes are an amazing bargain.    

I'm using the Studio 10's with a little 8" Paradigm Monitor 8 sub and liking it. That little sub puts out some good bass.
