how good signal cable?

I know two people who run the Dali Euphonia M4 Speakers ($8K a pair) with Signal speaker cable. You have to find the cable that best suits your ears, but yes, they are that good.

I have not used the signal cable, I have used only Acoustic Zen Satori and Alpha Core m12 and I like the Alpha Core very much in my system and it is in the price range you are talking about. In addition, they are flat and tough and can be placed under carpets between doorways, etc. which can be important in certain applications. I have talked with Bob Lee at Acoustic Zen and he is an incredibly personable man and they aim to please. They are very different sounding and either might be good in your system.

I use the signal double run for the bass of my Proac Studios. And I use Aperature silver for the upper end. I tried the Signal bi-wired and really didn't enjoy the top end as much as I did with the silver. I bought the shotgun version so I just doubled it up on the bass connection. Cables differ greatly, so you never know what you will like. Signal does offer your money back for 30 days I think. So if you don't like it, send it back. I am on my 2nd week about with the copper cable. I am still deciding whether I want to keep it or not.
I have used their interconnects before and did not like them very much. But, a lot of people do. And it is just finding what you are looking for. All of their cables do seem well made. I have tried many different types and brands of interconnects and speaker cables. Even the $2000 kind. Didn't like them either. I guess I am a tough person to please. Well, Joe at Discovery has made me a very happy man. I am buying a new phono cable from him right now. I really like all of his stuff. You can get great deals with no frills just like you can with signal.

Has anyone tried Signal's new silver cable?
