I have an all Ayre system (with Vandersteen speakers). I’m hearing a kind of metallic sound from the system which I’d like to pin down. As I stated above, its totally balanced from cartridge/CD player through the amp. I even removed the tweeter and mid from the boxes, sent them to Vandersteen who deemed them in excellent health. A while back I tried different XLR cables which had a minimal effect on the total sound....but that was awhile ago (Wireworld top of the line). I’m sure my hearing has changed (I’m a violinist and sit next to the piccolo) and just thinking about change. My amp is about 14/15 feet from the preamp, and no one has that length to try without a firm purchase.......still thinking. Re: Cardas......no luck with that brand. Colleen Cardas told me that it probably needed more time to break in (months?)....although I haven’t heard their newest offerings.
