AudioQuest Columbia interconnects

[Lance B]

I have just purchased a set of RCA AudioQuest Columbia interconnects for my Marantz SA7001 KI SACD player to my Plinius 9200 amp. Previously I had a set of Monster Cables from 20 years ago.
These new interconnects have a battery which supplies a voltage to the ground to keep it charged.
I have only had them playing music for about 3 hours, but I am not sure what to make of them. They sound good, but also a little strange in some way but I cannot put my finger on it. I don't whether it is the natural decay that is missing or what.
Bass seems tighter and there is plenty there and the stereo image is rock solid in the centre but with this mid range that is rock solid in the middle it also seems to make it louder and more piercing due to its pinpoint sound source. It is quite amazing to hear how these cables have made the stereo image so pinpoint, which I didn't think could be achieved to this amount.
Should I let the cables "burn in" more and if so for how long?
Has anyone else tried these cables or anything like it in the AudioQuest range?
Any suggestions?
