Tony,

If you don't mind my saying so I find that slightly patronising.

I don't dispute Tones knowledge........hes clearly an extremely bright (+ knowledgeable) gentleman......you quote that he is a "scientific patent attorney"......very impressive....it doesn't make his ears any better or worse though. 

Tones, by his own admission, would  rather listen to his cds than experiment with diff cables.  Nothing wrong with that.  Its just says to me he has little interest in audio tweaking.....

I don't know Markus....he didn't here anything?  Plenty have!

(not "a couple" BTW........I think several...which statistcally, whist hardly conclusive, starts making a difference, especially as some were appararntly quite dramatic)

As a matter of interest, If I was htinking (able to) buy one of these things I WOULD do  consderably more to find out its mechanics than I have .......been busy else where.  So far i've just contended myself with petes demo.

Yes, I can understand a degree of sceptism (have YOU tied one Tony?) but I don't necessarly think for your given reasons.

edit...sorry, your point a)......haven't read the blurb at all.  (Maybe its a good thing!)
