Gerry - some cable architecture have changed considerably, resulting in some pretty significant improvements.
One company that takes a completely different approach is KLE Innovations
I have been able to try most of their cables and they provide significant improvements over most of their competition.
I currently have the gZero2 speaker cables on my AV system and their gZero6 on my audio system.
Improvements include better dynamics, much deeper and much better controlled bass, very wide image and improved clarity and detailing.
Just Google KLE Innovations and read some of the pretty compelling reviews on their web site
I can also recommend their IC's - I have the gZero20's
