Kimber PBJ versus DNM Reson interconnects

I am about to purchase either one of the said interconnects. I won't have the luxury to do an A/B comparison. This cable will go between my Assemblage DAC2 (w/upgrades) to my PS Audio 5.6 preamp. Rest of my system is as follows:
PS Audio Delta 100 amp
Esoteric 700 transport
Mirage OM-7 speakers
Alpha Core Micro Purls silver between amp-preamp
Monster M1.4 speaker cables
Cardas Lighning Digital cable
Any suggestions as to what cable I should go for? I had these interconnects before and as far as I remember, they both have the same sort of sonic characteristics: upfront, lively, transparent - good cables for the money. Comments????
