speaker cable; what to do?

Aball,

$500.00 or less for two channels. I run a bryston 3B ST with the Reference 60v2s. LOVE THEM as well.

Thanks everyone for responding! :)

My sources are an Arcam CD92, Magnum Dynalab 101 Tuner and a Beogram 3404 TT. Speaker placement is good: 6-7' apart, 8-9 from couch, 2 from rear wall and 7 from sides. Changing location is not an option. I like the sound now, but I'd like to squeeze as much out of the system as possible. MORE MORE MORE! I'm sure everyone relates to that! :)
From what I've hear so far, I should hear a positive difference with better cable i.e. anything other than the home depot 12awg zip cord I'm using currently.
Moving the electronics closer isn't really an option for a couple of reasons; the "honey do" list is too long to warrant a battle at this time. :) So upgrading the speaker cable is the way to go. I could move the power amp but that puts the long ICs out of my budget.

Again. thanks for the help. Please feel free to comment on my ramblings. I like the abuse :) :)
