Rathbone,
After a little over 100 hours on the speaker cables I think they sound pretty good. I wouldn't describe them as you have though, they have plenty of excitement and extension both top and bottom. My only fear was of the midrange and it came around nicely.
I think I have come to the conclusion that they aren't the best match with my S&B TVC preamp. Although they sound good, I have had better results with an active preamp in the chain with the AP cables. So I have one on the way and will be selling my trannies and Seiden switch here on the 'Gon. But anyway, I digress. These are great speaker cables, especially when considering the price. At some point I may investigatate the ICs too.
