AZ Matrix Ref 2, Audio Metallurgy GA-0, Pure Note

The GA-0's are the best cables I've ever heard, period. I presently have them in my two systems with stunningly good results. Unfortunately, I don't believe they make them in long lengths due to their construction.

Then again, the Audio Metallury makes excellent speaker cables in long lengths. If you could get by with using shorter GA-0 interconnects and longer speaker cables it could be well worth your efforts to change your setup around that way... You could call Sandi at AM and ask her advice.

I believe AM offers a money back guarantee if you're not satisfied. In my view, they don't have much to worry about.

I have compared the AZ Matrix Ref. 2 to the the enhanced Paragon. The Paragon was more musical IMO. Full bodied for a silver cable with nice bottom. No experience with the GA-0. Of course this is my opinion in my system. YMMV. Good luck.
