I've been reading this thread with great interest and have found your experiences and dealings with designers of speaker cables particularly valuable.
At the risk of inviting you into another area of controversy, which I do because of your knowledge of MIT cables, what do you think of the various filtering/grounding techniques used in MIT, Taralabs cables. In my own case I use Entreq cables and i/cs with their grounding boxes which I have found to be extremely effective in reducing the noise floor and producing a natural, transparent and musical sound to my ears.
Full details of my system are on my profile which you might find helpful.
Given your joint substantial expertise and experience I would be very interested to read your responses and hope that is not too much to ask.
