Firstly, Dynaudio make terrific speakers so there is little concern you won;t like them - the 82 s probably your best bet here between the three because it's a pretyt good all rounder and offers good scale - I find the Contour line a bit less of a good deal simply because the competition gets stiffer as the price rises. For instance the Dane 82 is terrific becuase it is compeing against speakers like the Paradigm Studio 100 or a B&W 704 or maybe the 703 - to me the 82 is easily superior to these speakers and better yet not as expenive than some of them - and with 20% off a no brainer - but this is just my taste - certainly YOU want to go listen to those as you may feel differently. I think the B&W's look a little nicer if that matter and to some it does - they look so good it can trick you into thinking they sound better than they do - PERHAPS.

My main suggestion though is to take your time and listen to a lot fo other brands - the main reason is two fold - you may find something you like better than the Dynaudio's - OR - you may go look around and end up REALLY knowing that the Danes were the best for you after all which can ake you feel even better about buying them.

As some noted the Danes are 4ohm - So you will need some power - a 4 ohm stable and probably a 2 ohm stable amplifier. This may be a reservation for you because you need a good quality (though not necessarily high watts) to drive these to a very nice level.

Since you're in California and you like Classical and Jazz - I will make a suggestion to listen to some Audio Note speakers - these are high efficient speakers and a different presentation - they can be quite a bit more money than what you're looking at but if you consider a standmount speaker the Audio Note K/Spe falls around your budget and can be placed fairly near wall and in corners. You will get a very tuneful bass presentation and quite deep in a room the size of yours. Here is the directory of dealers in the US - some may also carry Dynaudio. http://www.audionote.co.uk/distributor/dist_nam.htm
The main reason I'm mentioning this is because they perform very well at lower volume which is important for living in an apartment as I do.

Still if you're set on the Danes you'll be happy I'm sure.
