well stated, tbg.
i have suggested blind testing but mr b avoids the subject.
practically speaking, if you can hear a difference and are confident that you do during a number of listening sessions, it should be sufficient. if you then purchase the cable and it remains in your system for a period of time, that also should be sufficient. blind tests are imlpicitly or explicitly rigged to make it difficult to observe differences.
