Audiolabyrinth, I agree with what you say about Rick being a nice guy with Much knowledge. I do take issue when anyone says one type of metal contact sounds the same as another because that is not true in my experience. (This could be a long conversation best left to another thread) In this case it's a small matter because the bigger issue is the improvement in sound of the URR is because of the Gold Helix Waveguide design works better than the UR Waveguide design.
Perhaps Rick will incorporate the Helix design into other products in the future.
