Well I received the Corelli with its power cord and have now tried it in my digital dedicated line and also the analog line.
First, I must mention the noise suppression items that I have already in place because I think its significant.
I am using a Bybee AC Module Crystal, (10) HF MC-0.5's on each dedicated line. In addition to that I also have the Bybee IQSE's in each of my components and also in my DIY power strips. And each line is powered through CPT 1800/300 units.
I mention all of this to put my review (opinion) in perspective.
I have found that the Corelli does change the sound. The soundstage does indeed go back further.
But... at the expense of the realism of the music. With the Corelli the music takes on sort of a fake sound. That is, full rounder music/notes are transformed to a stale sound.
Now perhaps it needs more time to settle? But at this moment I can't see keeping this unit. And, at the price of $2200! Nice metal box though.
I have read many of the on line glowing reviews and the high praise for the Corelli in this thread and I don't doubt that it works fine in many systems. So, it must be some interaction with the noise reduction devices that I have in my system. I suspect namely the Bybee units.
I will let it play for a few more days before I send it back. My suggestion is to try this unit with your system before sinking $2200.
