I've had three sets of VSA speakers since 1996 and have used various brands. In 2011, I auditioned the MasterBuilt Signature series in my VR5 Anniversary based system which were a big improvement. I'm using a full loom of balanced interconnects, speaker cables (in a biamping configuration), and power cords. The last addition that I made was the power cords. I was surprised that they made such a impact (tremendous improvement in the bass focus and impact).
I've moved up to the MasterBuilt Ultra series in my VR100 system, but all four of the MB lines have the same top to bottom signature of high resolution, detail, and bass power. Above all, they provide a musicality second to none in terms of dynamics, instrumental timbre, soundstage, low level resolution, etc..
There are four MB lines: Performance, Reference, Signature, and Ultra. After the introduction of Ultra, the Performance line was developed. That Performance line would be a good match with your VR-44's, unless you can opt for one of the other MB lines. If you do give them a listen, include power cords in your set.
Best,
Robert
