I've had cables make more difference in sound quality than component changes. That being said, I've not heard those particular cables. Don't make any judgements until you've run current through them continually for 200 hours.
Just Pulled The Trigger
Bought a new, 2m run of Cardas Golden Reference Bi-Wire speaker cable with 9mm spades. Cost me $1,450 with a trade-in of my 11 year old Neutral Reference Bi-Wire. The GR is now a "legacy product" and is still available on a limited basis at a discounted price. The retail on the GR was about $2,500. Although I am very much looking forward to the upgrade, to be used in conjunction with my Cardas GR ICs, I can't believe that I just spent that much for speaker wire. Hopefully, this is not a situation where a fool and his money are soon parted. What do you think? Please, be kind.
