Guy's, sorry for asking but why are you all so worried about arrows and which way you are hooking ic's up?
John, not worried -- just curious about changes from Grover. I doubt I've ever heard much of a difference in changing a new cable's direction, but certainly have heard break-in improvements. I suspect that if I reverse the direction of a cable after it's been broken in, it will change sonically until broken in again. Just a guess on my part - doubt I'll test that theory, but if it's true, it may be that some manufacturers label direction because they already run it in to some extent before shipping. And, of course, if you buy them used, it'd be nice to know what direction they had been used.
Rich, thanks for the reference on Rosenblat's book.... gotta check that out.
