2 Acoustic Zen Silver Reference II IC's too much?

Antonkk, at one time in my system I had all Acoustic Zen wires, 4 pairs of Silver Reference 11's, and they did not add any "brightness" at all. Just great details/speed, liquidity, natural timbres and a large and layered soundstage. The Matrix is a great cable for the money, however with your gear I believe to use a cable that adds a touch of warmth, but is not as transparent/detailed is not necessary.

It will be too much based on my experience.

I had MatrixII/SilverII, MatrixII/Matrix II, SilverII/Silver II and prefered MatrixII/SilverII combo.

brightness was not even an issue when using 2 pairs of Silver II. well, it was but not the main issue.

sound was very artificial and that was the major turn off for me. everyone's taste is different and it depends on the speakers, but if now you say that you would may be prefer a slightly softer sound, do not get 2 pairs of Silver Ref II.

I think Matrix II are great value for the money. You can combine them with your Silver II but I would say it would be a safe bet to have 2 Matrix IIs and omit the Silver II altogether.

What speakers are you using? Especially if the speakers have metal dome tweeters, forget 2 pairs of Silver II.

I've used the matrix and the silver ref II, and the Silver Ref II is a significantly better cable, imho. I've never had a brightness issue and would not be concerned about using more than one.
