well, the ICs i'm using are pretty generic. Audio research, I think the brand is... cost $25 or so. i have a pair of silver ICs coming to me in the mail, but they're not here yet. I'll see what happens when I add them.
yeh, i'm guilty of not listening to it first, but i don't have a dealer who will loan me out equipment. the sound is different, but i'm not necessarily sure that the sound is all that much better... i mean, it's much more subjective. the change in amp was DEFINITELY better... no one would say otherwise.
i'm amazed that the unit retails for 6K... that's 20 times the amount of my cd changer. 20 times!
i'm going to wait for the ICs, listen for a couple weeks, and if i can't justify the expense, i'll hopefully be able to sell it for what i paid, or close to it...
this has been very interesting though... changes in digital equipment don't seem to mean much, even in a system with relatively revealing speakers.
