I've had several families of cables in my system including Fulton, Monster, Audioquest, Synergistic Research, Kimber, PS Audio, and Signal Cable to name a few. Of all these mentioned and not, my favorite are the Signal Cable. I do favor using the same cables through out the system whenever possible.
With Signal Cable one does not get a lot of fancy boxes or audio jewelry but one does get cables that are true sounding, honestly built and priced, and cables that to me sound more like real music. They are capable of throwing a 3d soundstage, realistic dynamics, bass that is tuneful yet a force to be reckoned with, and can reveal the timbre and colors of both instrument and voice. All at prices that just seem stupid compared to today's state of the art.
Frank, the owner of Signal Cable is happy to discuss your system and your goals for it. And surprise, surprise, even if you have the money and inclination to buy all of his top of the line Silver Resolution cables he will probably not recommend this choice unless he thinks that is best for your system. In my system he recommended and I use a combination of his copper Ultra speaker cables, Silver Resolutiion interconnects, Magic and Digital Magic power cords, and his HDMI cable between my PWT and PWD.
Signal Cable joins an excellent cadre of companies that give superb results for the money with sound that is to die for that includes: Legacy Audio, PS Audio, and Herbie's Audio Lab. All these products are at least designed and manufactured here in the USA though some parts might be born in other countries.
Call Frank at Signal Cable and give his stuff a try, there may be cables that do some things better but few that get as much of the music right.
