XLR to RCA Adapter Dilemma

Thanks for the responses, folks. Yes, Al, I am using the adapter at the preamp out only, and then plugging into the power amp directly with the rca. Also, I am using the same rca to rca cable. I have a/b'd this ad nauseum, and my ears continue to conclude that using the adapters through the balanced output of the preamp results in greater clarity and volume over the rca to rca connection. To be certain that it just wasn't "me," I had my wife listen to the system and she came to the same conclusion.

Also, to Elizabeth ... thanks for validating that practical application can trump theory. For a minute there, I was beginning to doubt myself because the theorists maintained that what I was hearing was simply impossible. I feel much better now.

Unfortunately, my amp is not at all balanced, and I'm not looking to replace it since I like it just fine, and would rather save the dough. So, for now, it's adapter city for me. I may just contact Signal Cable and inquire about custom adapters. Thanks.
