I need advice on which speaker

Magnolia/Best Buy has a very liberal return policy and for the sake of a 75 mile drive, suggest you take advantage of this and buy a few a pairs knowing you can get a full refund from them.

B&W's have metal tweeters or in the case of their 800 series, synthetic diamonds.  Sonus Fabers have soft dome tweeters and both brands sound pretty dissimilar from one another.  It up to you to decide which you like better.  I think your on the track here.  Good luck! 

Just like mesch, I agree.  Reread chrshanl37s post.  

I also like this approach to find the a speaker that is "best for you".  And not someone else.  While it may be impractical for some to buy several pairs and then sell them off, you can order a pair at a time, audition them and return the pair you don't like often within a very liberal amount of time.  The point is to be able to audition them in your room and with your electronics.   Good luck! 

Id feel a little guilty buying a few pair of speakers from Best buy and returning all of them.

So would I.  But I would not feel guilty if I tested a few pairs and bought at least one of them.  I assumed this is what you were going to do as your initial post said that auditioning was a bit of a challenge and the your nearest Magnolia was 75 miles away.
