Help-IC's needed AU or AQ

Over the christmas break I got a chance to try the
cheetah's. Very nice- things seemed sharper, more
detailed, and with a little more bass. I especially liked
the grab of the connectors,quite snug, probably since
my cardas are so old. My only concern with a short audition
is sometimes one wonders if you are hearing things for real-
or are you hearing things that you read about. Overall I
did seem to enjoy the music more and thats whats it's all about. I'll try to audition the AU24's as well as the AZ ref.2's in the next week or so. Any other thoughts-I would
love to hear them.
Thanks for all your inputs.

Thanks for all the input. I ended up buying a used/new pair of Sky here
on Audiogon.Just hooked them up last night(Sunday),
initially I feel like my system has never sounded better.
It is a little too soon to be sure of course, I will try
to relay my impressions in a month or so if anyone is interested.
I believe that with Sky my ic's are good enough that
further cable auditioning really is not going to make a
significant difference.As I stated in my initial question,
my goal was to buy a good cable and be done with it.
Any thoughts welcome.
Thanks.
