In December this is what we did:
We recently ran comparisons on cables:
silver cable from QED,
“snowline” from Van den Hul
and ordinary Jaycar 4mm cable.
The consensus was that the silver cable sounded bright, almost tinny, and female voice wasn’t as rich as with the copper cables. The next test was using the same cables with different loudspeakers, the results were inconsistent, but still in line with silver sounding brighter than coppper. This could work in favour of dull speakers. More tests will follow!
Since listening to different cables W has bought the Van Den Hul cable, his comments are eagerly awaited.
