I was fortunate enough to find a Mccormack DNA-1 Deluxe at a very reasonable price. Yesterday I switched out my emotiva mps-1 and replaced it with the DNA-1 and what a difference. Until now I was imagining soundstage depth...now I know what it means to have depth. In every respect the amp does a better job driving the maggies then my old amp. There is more high-end detail, more shimmer, and more bass. I am just thrilled with this new purchase and just want to share.
