I personally have been very disappointed with monster cable. Their business model seems driven by marketing, not engineering. That debate aside, for the price of those cables you should get WBT connectors, instead of turbines. Both are RCA's, but the wbt's tighten up for a much better connection. I use Siltechs, which have wbt's, but most high-end brands use them or similiar design. To get an idea check out this link:
