My setup is CA 640 v2 amp + cdp and speakers are MA RS6, currently using SA XT speaker cables and QED Qunex 2 IC. Planning to upgrade the speaker cables, and I just don't know which cables to choose from - Chord Odyssey 2 or QED Revelation - for my setup, both have excellent reviews from forum folks who've used them. Would be glad to know why Dan changed from Chord again to QED Revelation ? - Need to buy it tomorrow. Thanks.
