Twopippis,
Thanks for your reply. You have me tempted. How do you have your cables positioned. Side by side or separated by a few inches or a foot? Do you find the bass fuller? More speed would be ideal but the Onyx are so fast it is incredible. Esp compared to other speaker cables. I would add that I have a massive soundstage, but do lack the last bit of three dimensionality. On the other hand, if I had more treble extension I wonder if it would be a good thing. I might just do it. Thank you again.
