Cables do make a difference. What is interesting to me is that it may take me awhile to decide if the difference is correct. Some cables that wowed at first became irritating two weeks later. My long term reference Alpha Core MI1's sounded bad with my new Mobile Fidelity OML 1's. I purchased the AQ Slates and they are great with the OML 1's. I have found component interaction plays a part in rather a cable is successful or not. Some of these differences would not be apparent in an A B test.

I wonder if sitting 7 feet from my speakers makes it easier to hear cable differences?Would I hear the same cable effects from 15 feet from the speaker? Would I be able to detect cable differences in a multi channel system as easily as I do in my two channel system? Since many of our systems are configured differently and in different acoustic spaces cable differences may be more or less obvious. If you do not hear the differences in cables buy inexpensive. If you do hear differences it is worth the time and effort to try cables to get the best system synergy.
