Thank you all for the info. The speaker wire was a kit and I heard that silver was the best, so for the price I went for it. It is 15 awg cable consisting of a 22 awg, 20 awg and a 18 awg 5N silver wire. For the 6 foot pair, the cost was $229.00 and 2.5 hours of labor. I listened last night for about an hour and it did not seem quite as bad as before. Only time will tell.
Does silver speaker wire sound bright?
I purchased a kit of 99.999% pure silver speaker wire with PTFE insulation and assembled it. I installed it on my system and it seems to scream at me. My system is all tube (Melos)and my speakers are the North Creek Rhythm. I use the preamp also as a headphone amp and use Grado SR325's. The headphones are not bright they lean tward a little dark sounding. I feel the brightness is in the cables and wounder if they will mellow with age, and how long will it take?
