Where are you located Flamenko ? If in the UK then you are more than welcome to come around and listen to it for yourself. Greg
Answering your question: Both are sharing exactly the same circuit and components pool, the silver is obviously silver wired. Internal silver wiring brings more refined sound to the table but, IMHO, to take a full advantage of that the rest of the TT set up need to be rather good too as well as the system wire needs to be well voiced to maximise that gain.
ps: sorry for the late input but I am not regular forum checker.
