My system is also mostly Quattro and various different Siltech. I find the Quattro betters the Siltech except in the bass. I hear slightly more detail in the bass with the Siltech. (In my system of course.)
Nordost Valhalla vs. Acoustic Zen
Has anyone had a chance to compare the Nordost Valhalla line to Acoustic Zen? I replaced Quattro Fil/SPM with Silver Ref/Satori and found that in my system it betters the Nordost cables, or any other cable I have tried.
