TARA REF. Gen + Speaker Cable vs. A. Zen SATORI?

I am using the TARA Ref. Gen + speaker cables between my VTL 225 triode monoblocks and Dalquist DQ 20's. Have a VTL 5.5 Tube preamp with Tara Master Ref/Gen'l interconnects thru-out. I believe my system could sound less dark, a bit more brighter in the mid & hi's with more dyanamics and presence.
The reviews & press on the A. Zen Satori's are very positve. Does anyone have thoughts on what may do the 'tweak'? Was also considering demo-ing Red Dawn II's. thanks
