Well, they arrived and I played some favorite tracks before swapping cables. The quick A/B comparison was a surprise

. How dare these cables sound so good.

They cost substantially less than the cables I took out. The only side bar is the adaptors supplied with the SoA2K fell apart as I unplugged the original cables. I will spend some quality listening time this weekend. If the Nitros sound this good, I wonder about the Summit.
I will report more after an extended listening.
