I also am limited on time this evening. I can provide a brief outline of some of the testing I’ve been involved in.
Some of the earliest test used the Clark switching device (I forget the official name of this unit) used by Stereo Review during their “infamous” cable test. I believed it would allow different cables to be switched remotely and randomly as well. Many audiophiles including myself question the transparency of the device originally. We then bypassed the switcher unit with identical cables to a different input on the preamp and used the preamp as a switcher to compare the Clark unit inline verse the bypass. All tests were matched to less than one tenth of a db. Through multiple tests I did not achieve a score that showed any significant preference. Later we also used custom designed switchers with high grade contacts that had a computer scoring system which could be programmed to conduct AB, ABX, AA, BB testing randomly or by any combination requested. It is truly amazing how often you will identify AA or BB as being different components when conducting a blind test. As I mentioned I participate in these tests during the course of a few years…about the same time it took me to begin altering my views.
All this really means little. I participated in many tests, I altered my opinion, and nothing that I have experienced during my on going love for music and audio has changed that. Maybe someday something will. Once again, this is only my experience…YMMV!
Best regards, Tom Garcia
