Does anyone have experience using 6-8 foot runs with Markertek balanced cables? http://www.markertek.com/MTStore/Sto...aseItem=SC3XXJ Currently I am using Cat Cables top end copper RCA interconnects connected from my power amp to a receiver. I thought perhaps because I am buying a new pre-pro that has the ability to use balanced connections, these may be an improvement over the RCA connections. These cables are reasonable in cost compared to other balanced cables that I have seen on the net. They almost seem cheap compared to what I paid for the Cat's. The context of the word cheap here is not negative in nature. Would there be an advantage using balanced connections compared to the Cat's and does Markertek provide good quality products? These cables are very reasonable in cost but I don't want to just throw money away if it is not worth it. Any thoughts or suggestions would be appreciated.
