Against everything that high end cables stand for

I just received a pair of Michael Green speaker cables. 10 ft pairs, $2 ft, totaL cost $40. They are unterminated bare wire and appear to be 3 twisted solid core 20 gauge wires. I spoke with an employee of MGD and he stated that they do not recommend terminations of cables as the spades, and required solder only serve to add more colouration. My impressions from 2 hours of initial listening, is that vs other wires Ive tried, it trounced my Yamamura m4000 and PAD cables in every area except bass definition. I will give them further listening this eve, but MGD has these theories that make logical sense (Tuneable Speaker, Room Treatments, Clamping Components, Racks etc) which to the T so far have resulted in sonic superiority and improvement.
