Budget floorstanders under $500 ?

With the size of your room, why not go with a larger--and more refined--monitor? At the price range you're looking in, you could get a lot more for your money (especially buying used, and assuming you already have stands). Check out speakers from KEF's older Q (Q15 is great: look on eBay) or newer iQ lines. They're front ported (great for a small room) and have ~90dB sensitivity, which would work well with your Jolida. KEFs have a great, warm sound with a beautiful midrange that would suit your listening tastes ideally. I have a considerably more expensive pair of Vandersteens now, but I still miss my Q15s: they really got voices right. As I recall, they went to the mid-50s in the bass. Always sounded great in even medium-sized rooms. A step to floorstanders at the price you're considering would likely be a step sideways.

Thanks, I hadn't really thought of going that way. I have Target stands filled with shot, so I'm good to go.

In terms of "a step sideways" with regards to the floorstanders...are you saying that the increase in low frequency response would be offset by decrease overall performance from my current Missions?

Triangle Heliade new for 699.99 used around $400-500.

Sensitivity: 90dB
Freq. Response: 50Hz - 20kHz (+/- 3dB)
Impedance (Nominal / Minimum): 8 / 4
Dimensions (inches): 38.2H x 7.9W x 13.4D

I use Triangle Comete monitors with my Primaluna PL2 and love the sound decent bass, room is 12 x 24

I found a pair of Vandersteen 1c - just barely broken in, here on Audiogon for $550. They'd be great for the kind of music you like.
