I agree with Kal that XLRs are the way to go. I use them whenever there is the option to do so. The superior connector IMHO.
anyone else hate locking RCAs?
I find that whenever I tighten a locking RCA connector even a little bit, it becomes a battle (and one that I fear will result in casulties -- the rca connectors, the cable, the rca inptus). Lately, I find myself unwilling to tighten them at all. And then the barrels are always falling off and getting lost. Just give me a nice regular connector any day.
