Analysis Plus Silver Apex Speaker cable

Hi All, I am a fan of Analysis Plus for several years now. I've tried several of their cables having been generally satisfied with the upgrades along the way. I just bought a pair of the new Silver Apex speaker cables. I've been listening for about one week so far. This is definitely a dynamic cable! Sometimes with improvements comes a down side. As I said, this cable is dynamic. A large sound stage with really nice bass on the up side. On the down side, it's bright on my Snell Type B's. I know that silver has a reputation for being bright. I was wondering if it's the age of my tweeters? Perhaps a shortcoming on the now 28 year crossover? I called the company today and spoke with a rep from AP. He basically said that he wasn't familiar with my speakers so he had no advice. Nice! I asked what speakers they used to test their cables on. One set was Watt Puppies. Another was a ribbon speaker from Australia (I wrote the brand down at work and left the note there). Another set of speakers they had on hand was Von  Schweikert. Who among you are using (and enjoying these cables? Any help is appreciated. Oh ,my equipment consists of PS Audio Directstream DAC and transport, Pass Labs XP20 and Pass 250.8 amp. Cabling is AP. Thank you. Joe
