Need help on speaker selection

Marco, I wouldn't be too hasty with those words regarding recent Klipsch designs! I have heard many Klipsch speaker designs over the years, and was never impressed really...including the older "classic klipsch" stuff likey you're mentioning.
I was an owner of such high end speakers as Thiel 1.5's and 2.3's, SF Electa Amators(originals), NHT 2.9's, PSB Stratus Silver I's, Merlin TSM-m's, Infinity Prelude MTS's, etc! I've also sold most every line out there in the main-stream at one time or another on a retail level, having worked for a few high end stores over the last 10 years. And the speakers I now use in my small room with a tube integrated amp driving em?...Klipsch SB-1's at $250 a pair retail! (actually, I'm going to SB-2's, which are better)...and I couldn't be happier for the time being!
These speakers shouldn't sound this good for what they are, but they do!..and I'm not changing any time soon. From HT, to rock, to delicate stuff, I'm thrilled with what these cheapie speakers can do! They are not supposed to be this good, but they are. The top end isn't what higher end speakers are ultimately, and midrange isn't as pure as some..but it's close. Pressence and dynamics are first rate, very neutral and transparent, and lots of detail!
For a small room esecially, there's not much that can compete with these for what you're lookiing for with a tube amp! They'll rock, they'll punch, and they'll finess as well. Best little speakers I've had to date for the bucks...no kidding!

I bought a pair of green mountain audio europa's recently and am very happy with them. Two way time and phase aligned, marble composite cabinets. Overbuilt - read morel tweeters, audiomagic silver wiring, first order crossover - basically these things have increadible imaging, a coherence that is hard to beat, and increadible prat. You would not get the lowest bass as it has a 6" woofer, but these would be great to start with. They are highly efficient too! New I think they list at between $780 - $900 range. Give them a listen, they are worth seeking out.

Get an Oris 150 or 200 and LIVE

Vandy's have the ability of having abundant bass. However, Richard Vandersteen designed in compensation for a flatter response. I do know he did very elaborate designs on this for the Model 3 and Model 5. I do not know what he did for the 2 series. If he used similar compensation methods, then you should be able to adjust the speaker quite well, and it's a good choice because you are going to have a pretty serious bump around 75 Hz that's going to need to be tamed.

I've not heard the Vandy's but have heard good things about them. I owned a Jolida 302B for a while. Great little integrated amp, and I'd bet the 502 is as well. I'd consider pairing it off with a vintage Klipsch horn-loaded speaker. Heresys or Forte II's would both suit the range of your musical tastes well. The Forte's are substantially larger and kick out some more bass. The older Heresy's would take a bit of tweaking, but are very nice speakers overall and pair off nicely with tubes. Either of those would give you a handfull of $ back from your $800 budget and be very satisfying to listen to with the Jolida. They may take some looking for to find a local pair in great shape, but it would be worth the effort IMO. There are certainly other choices out there, but those have worked well for me. Big-bang-for-$. Don't even think about the current-production Klipsch that weren't designed by Paul W. Klipsch...you may as well by Bose, or perhaps something out of the back of a van if you live in an urban area.

Good luck!

Marco
