Hello again Markj and okvist
All good what you said. Silver should be a notch better than anything else now its the best 'normal' conductor we have available.
And even though I am somewhat skeptic about the benefit of most exotic cables, I am fully able to hear the difference between RCA adapters and a fully balanced signal path.
(When mentioning exotic, I do suspect we'll see some silly priced cables made from high temperature superconductors sometime in the future.) 
Anyhow I did jump into this thread because the Auditor do interest me, and I heard it. I view it as highly analytical, and that go well with the idea of listening for details with cans. The features it comes with do indeed remove the illusion of having the band playing between the ears - so next month I hope to be able to give the SPL a longer audition and then decide its worth the money.
