Well I decided to get my HK fixed and I am debating selling the JBL's and getting the Ascend's with a sub. I am really intrigued by the reviews of the CBM-170's as well as the HSU and SVS subs (i would get one or the other)and really interested in going to the sub/satellite type setup in place of my large towers but curious what some of you guys think if its not worth it or if I may even be dissapointed since the JBL's are pretty formidable for the price range I have a feeling I won't be able to play the Ascend's quite as loud but I am hoping for a little better SQ. Not that I dislike the JBL's but I am looking into an upgrade to get an even better sound, particularly a little more balance, fuller sound at lower volumes which I know good sub will do. For the record, I watch a lot of DVDs and listen to a lot of music too which is mostly rock, light to hard, acoustical and electric and I love a real clean accurate sound on the warmer side with nice full balanced and accurate bass. Living room size is about 13X20.
