Does silver speaker wire sound bright?

Definitely go all silver. The miscnception of silver sounding bright is because most so called silver cables are only silver plated on the outside. These cables definitely sound bright. However pure silver cables are more relaxed and liquid sounding than all copper cables. Not all copper cables are bad. I have also used some copper cables that sound very remarkable. The only difference is that pure silver is really liquid sounding. Try the kimber KCAG and also Audio Note Stuff

Some break in time silver cables does reduce the brightness. I noticed it more when I added Goertz Micro Purl silver interconnects than when I added a set of Light Star Audio silver speaker cables. After about 200 hours they sound wonderful together. The silver does give better detail and soundstaging in my system compaired to copper. Good luck.

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.
