help me decide speakers for two channel audio


Currently deciding between B&W 802 Nautilus, Wilson Audio Sophia 2. Von Schweikert VR5. Driving them with EAD sig preamp and lexicon two channel amp, using musical fidelity CD player. Buying used so auditioning not possible. Can consider any other brands in the same range.
girish
I have an option to buy 802 Nautilus for $4700 and Usher 8871 for $3200. Wilson Audio Sophia 2 is not available close by. Which one will be good for a decent size room 24x18. Driving with MC12 and RX amp.
Need to make a decision soon!!!!
I personally would buy neither and wait for the Wilsons. Heck, you already have 3 systems. What is an MC12 and RX amp, though?
