Ozzy, I have the D7 and use two pairs instead of jumpers. I find that two pairs of cables vs bi-wire or just a single run with jumpers give a better sound top to bottom. I found this to be with other brands I have also had in my system.
IMHO if budget permits go with two pairs.
Out of all the HiDiamond cables I have had in my system I found the D7 to be one of the best speaker cables at its price point and competes with more costly cables.
As far as the P3 and the #2 XLR cables, I did not found them to be any better then others brands in their price points. Not bad just not better.
I have been planing on selling my two pairs of D7 but have not had a chance yet to list them as work keeps getting in the way. So if you have any interest PM.
