B&W JM Labs or Paradigm Signature S8.....Help?

I am deciding on a new pair of speakers. I think I have narrowed it down to:

1. JM Labs electra 936
2. Jm Labs electra 946
3. B & W 803D
4. Paradigm Signature S8

I understand that the JM 946 and B&W 803D cost about $2k more than the JM 936 and S8's.

My questions are:

1. Which will give the best sound quality in a small/mediam size room. (14' x 20' x 10'high) Hard wood floors.

2. I have not decided on amps yet. (different thread, maybe later)

3. I listen to 2 channel CD's and Home theater.

4. I have not heard any of these speakers. I am only going by specifications and reviews

Has anyone heard all of these speakers to compair?

Thanks for any help,

Danny
