Sorry to state but sounds like both of your are behind the times. The gentlemen that made those cables, Robert Lee, has started a new company called Acoustic Zen. His latest cable design totally outclasses his earlier HT designs. If you've not tried them, well you owe it to yourself before spending money on a antiquated concept. They were, and still are an excellent value, but after extensive side by side comparsions, I don't believe they're even close to what Robert Lee has accomplished in his newer design.
Example: Stereo Times reviewer Jim Merod said they are the best cables he's ever auditioned and reviewed....and he was no fan of HT when they first became the rage some years back preferring the Nordost over the HT's easily. Well, this time around when comparing his reference to the Nordost, he too had to admit the Acoustic Zen is the best he's come across.
The Pro 11's are good, the Pro 9's are better while the Acoustic Zen kill them both.
