Sorry. Didn't see the equipment listing. Silver wire I don't think would tame the highs. Maybe Conrad Johnson stuff? Hmmm, I've got B&W 602's in my bedroom hooked up to a Rogue integrated. That helped tame the brightness a lot in my system. You might try a different speaker, like a JM Cobalt, and see how it responds to your gear. That would help isolate whether you need new amps or new speakers.
