I've not had the chance to try out the Dominus power cords, but I have tried out numerous pc's on my Krell KRC-HR, so I thought you might be interested in this. By far and away the best pc I've mated with the KRC-HR is the Cardas Golden Reference. It totally opens up the soundstage in all dimensions and images within the stage are correctly sized and proportioned. Even much more expensive cords like the Kimber Palladian (PK-10?) and Aregento Powercord 1 just didnt seem to energise the music like the Cardas did. Before you lay down some big green for the Dominus, try out the Cardas.
Another comment I might add is that you may be very surprised by trying out a current generation CD player. I have the Krell SACD Standard now and it leaves the old generation Krells in the dust. I spent a long time and lots of money on cables (incl Purist Musaeus, Venustas, and currently the A.K. Limited) trying to squeeze the last drop of performance from my system. I replaced the old Krell 300CD with the SACD Standard, and wow! All the qualities that were incrementally improved by the cable changes were suddenly there in spades. Just something to think about...
Cheers
