Wharfedale towers on ebay.. i am trying to decide between the 9.4 and the 9.6. obviously the 9.6 is much better, but it is going to work out as $175 more (9.6 is $425 + $35 shipping vs. 9.4 $289 free shipping). i don't know if the difference is going to make that much of a difference to my less-than-discerning ears. thoughts?
