Hi Dmitrydr,
I looked at this and your other related thread. I'm glad you're enjoying the Satoris. Right now you're working on two variables ie the CDP and the IC. I'd change your IC first. I think you'll be pleased at how the Matrix Ref (short run!) will open up the sound of your Marantz. They might have sounded a bit edgy with the NAD. If you're still not still not happy, then consider a different CDP but my guess is you won't need to (at least for a few months!).
