This past weekend I listened to a system which used a pair of Vandy Model 5 speakers. WOW! They were some of the best sounding speakers that I've ever heard. But, they were in a system which used Bel monoblock amps, a $6K preamp, and a $5K CD player, so, I'm not sure if what I was hearing was more due to superior electronics or the speakers themselves. Also, the store had the rear firing tweeters turned off. How does the rear firing tweeter affect the speaker's performance and do you use them, or turn them off? Finally, what is the best price on these speakers that anyone has found? Thanks for your help!
