I recently purchased a pair of Audience AU-24 speaker cables & I/C's based on the review. The Audience is a VERY THIN CABLE and easy to connect to my EAD TheaterMaster-8, PowerMaster 1000 and Bohlender Graebener planar speakers which are bi-amped. As compared to the Straight Wire Serenade and Virtuoso, the AU-24 is more musical with crystalline highs, a definite improvement on the treble post. Santana's Suernatural sounded magical with this cable. The Straight Wire Virtuoso provided much better mid-bass than the Serenade but I had a hard time discerning a large improvement between the Virtuoso and AU-24 when connected to the mid-bass post.
Caveat-- my speakers only go down to 80 hz and I am using a Sony 7700 DVD player (next upgrade project) with Nordost Silver Shadow Shadow digital cable. I really like what the AU-24 did to top-end and would recommend trying this cable. If wife acceptace factor is important the cable is thin and easy to hide.
