In 1969 Quad performed a double blind test on the best ears in the business. They used their old valve amps (2% distortion), the 33/303's (0.1% distortion)and 405 etc 0.001% - the golden ears could not reliably tell the difference. That was the last double blind test performed in the hifi industry that has been openly reported.On Mon, 27 Jan 2014 07:55:48 +0000 Tom <madtom1999@xxxxxxxxxxxxxx> wrote: Hello Tom,nowadays. I use mains cable. While you can show differences in performance they are irrelevant to human beings and generally orders ofI beg to differ; I changed my speaker cable from mains flex to low oxygen cables, and immediately noticed a difference. After the change, the first CD I played (one I was very familiar with) had bass notes I'd simply not heard before. You will have installed your cables and expected to hear a difference and been more attentive to the sound - you may also have heard more as bending down to connect the cables often clears the sinuses and eustation tubes which will improve your hearing. If you had performed a double blind test the chances of you being able to statistically notice any difference due to a fractional change (if any) in the resistance of the connection between speaker and amp are pretty much zero. The circulation of air due to closing a door has orders of magnitude more effect on the sound. Tom te tom te tom |
