Does silver speaker wire sound bright?

I didn't realize you had bi-wire connections. Yes, by all means, try doing that.

All the silver interconnects and speaker cable I've had in my system have sounded different, just like all the copper ones. Break in is a factor, but I will admit that it's easier to have a bright silver cable than a bright copper one. There are other more important factors though, like AWG (for DC resistance), impedance, capacitance, etc..............I'm beginning to think that the little cheap MIT Terminator 3 speaker cable is better overall than my AudioTruth Dragon Plus, so the conductor material isn't always pivotal. Some guys swear by the carbon fibre conductors in Van den Hul cables, but I've never heard them.

IMHO, you would have been better off just buying Music Metre Silver. It's 13 AWG, and I got mine for only $175 (a six foot pair). It's not manufactured anymore, but with a little searching, it's not that hard to find..............Anyway, I feel that any speaker cable whose gauge totals less than around 13 is going to have a tendancy toward brightness, except with single ended triode tube amps.

And it won't be, with just a 15 gauge speaker cable. Going from 10 gauge to 13 gauge makes a huge difference, so going from 13 to 15 would be noticeable also. The higher series DC resistance of a smaller cable will always have this effect, unless it's a network terminated cable. However, if your amp has a low damping factor, it is limited in the degree to which it can reproduce dynamics and bass extension/slam in the first place. My Krell amp has high current capability, but a lowish damping factor (like 50), and I've found that I can only go so big with speaker cable gauge, before the entire frequency range loses focus. I ATTRIBUTE THIS to the higher capacitance that always accompanies higher cross sectional conductor area. However, not all cables of the same gauge sound the same, or arrange their conductors the same, so I still experiment with it. You have to find a balance between the speed you want with a low capaciatance/high resistance cable, and a low resistance/high capacitance cable.......................I've seen some cable advertisements that claim you can have both, but you can't. All you need to do is look at their own published specs, and you discover that they certainly have not circumvented physics with some kind of "magic".............Personally, I'm to the point where I'm liking chaep MIT speaker cables over my expensive silver ones...and it's NOT because my Krell amp is "cold and analytical", either.
