If I can just interject......I just took delivery on a couple of the new AQ Hurricane PC's. I have had most of the TOL Shunyata's up until the most recen NR. The Shunyata cables I thought were extremely good and hard to beat and still do. I didn't think the Alpha line was quite up to par with competing brands in same price range, and since I needed three power cables and two digital aes/ebu (and didn't want to spend mega, mega bucks), i decided to go with two of the new Sigma's for the digital, and so far no complaints with the AQ's. At the very least I am sure they are worth an audition (if this is one of your considerations).
