Does silver speaker wire sound bright?


I purchased a kit of 99.999% pure silver speaker wire with PTFE insulation and assembled it. I installed it on my system and it seems to scream at me. My system is all tube (Melos)and my speakers are the North Creek Rhythm. I use the preamp also as a headphone amp and use Grado SR325's. The headphones are not bright they lean tward a little dark sounding. I feel the brightness is in the cables and wounder if they will mellow with age, and how long will it take?

1.Silver cables do sound bright, lean and harsh fresh out of the box. 2.Silver cables do need at least 2 weeks of continuous break-in. 3.Silver cables, once broken-in, will definitely sound smoother, more transparent, more detailed and neutral compared to any copper cable of the same design. 4.Silver cables will tend to have a lighter but more defined bass. 5.The advantage of silver is that it is a lot more audible in speaker cables than interconnects. 6.Audioquest silver cables are the least colored and mate well with most varieties of electronics and speakers. They are excellent with Thiel, B&W, Snell, Martin Logan and Apogee speakers, just to name a few of the big brands. These unanimous conclusions are based on extensive listening and blind test between myself, my brothers and friends. In fact, we all modified our speakers with silver wirings. If you know how to solder, I would strongly recommend it, but be very careful. Keep playing with your cables and they will sound great.
I am willing to wait for the sound to get better. Just to clairify, these cables are 99.999% pure silver, not copper, 15 AWG with no lug termination. I agree with Carl that the cable should be a larger AWG. I was not aware of the cable he mentioned and could not afford anything more. Maybe I could mate the cable with a reasonable cost copper one, and biwire using the silver for the tweeter and copper for the mid-bass. Any thoughts?
I didn't realize you had bi-wire connections. Yes, by all means, try doing that.
forgot to mention I have a pair of AUDIOQUEST .5m LAPIS x3 w/rcas for sale here. Asking $200 shpped
Stranded silver sounds more etched in my system, yet extremely detailed. Solid silver seems smooth sweet & more accurate in timbre. It depends on the brightness of the rest of your system and the listening room. I sometimes switch from stranded to solid silver to change the systems character,but always migrate back to the solid silver. Silver is a better conductor for interconnects but you have to be careful with its implementation. I tried changing a 2 inch long internal wire on my DAC from the stock common stranded copper to solid and stranded silver and it changed the sound of the unit for the worse- bright, etched, harsh, made only certain program material sound correct. Many times the designers try all types of internal wires in development and design a units "characteristic sound" around their choice of wire.
