Friends, I have come across a new type of listening test I want to describe and get your reaction to: Goal: Find out if sonic differences exist in speaker wire. Null Test: 1. Divide stereo in halves, each with its own cable. On left speaker, we place plain vanilla 12 guage wire. On the right, we place Cardas Golden Reference, my benchmark high end brand. 2. Switch preamp to mono mode to drive a mono signal to both speakers. Now at this point, we have an exact signal being sent over both wires with the same speaker load. 3. Use balance knob to switch from speaker to speaker. We can also listen simultaneously to both wires. Cover wire to hide cables. 4. Note any differences heard on a variety of program material, being careful not to develop listener fatigue which can skew the results. 5. Begin test with audience with more than casual listening ability. I think this is a good test, because of the following: a. Same signal path is assured for both wires. b. Ease of switching cables, without breaking and re-establishing connection points which can have a value and the real-time nature of the switch. No need for expensive cable comparator box. c. Listening simultaneously will highlight differences due to a different stereo image created if sonics not exactly the same. What do you think? What would you change? I may be able to create a test in NYC. Chu, does this work for you and your test parameters? My goal is simply a fair test whereby rock-bottom cable is compared to very well-designed and expensive speaker cable in a reasonable, easy to set up, and cost-effective environment.
