So many choices what to buy?

Audiogod2, thanks for your insight. Here's the details on my room.
I have a 16'x21' room with a fireplace on the short wall. Currently I have my speakers (Vandersteen 2Ce's) on either side with about 2' infront of the wall and 2' from the sides. My listening distance is about 18' from the speakers.
My electronics are a Krell KRC-HR with a KSA200S amp (200 wats per channel at 8 ohms. I was told I could arc weld with this baby).
I love all music so the desires change with the mood, Clasical, Pop, folk, rock, blues, jazz etc. so my speakers need to be able to cover the dynamic range of all the music moods I might find myself.
If can let me know your thoughts on this please do so I can make the selection.
As far as the Thiel's I have found that there are deals that will bring in the purchase at about 4800 for a pair, new. Seems hard to believe. do you think this is correct, or should I be very cautious of such a deal. The price certainly makes the speaker an attractive choice.
Please let me know.

Thanks for your response, as far as electronics I have a Krell KSA 200S Amp ( you can arc weld with this) and a KRC HR for a preamp.
THe second input was correct, I am interested in long term listening, quality, service etc. When you hear it in the dealers show room it is not my room. Everything will sound different.
Additionally when you analyse the sound I am initially wowed by the dynamics of a full range speaker but will I feel the "presure" of the music after a while?? SO with that said I am looking for a general consensus on all that i listed above.
Thanks again for your input.
