Alpha-Core MI-2's (cryo treated), 5' pair with speaker pins. $163 for the wire, $35 for the cryo.
Can't tell if the cryo helped at all...but, the Alpha Core was the first speaker cable bought that decidedly sounded like an upgrade, not a lateral move sideways.
I was a little concerned about the JVC driving this ultra-high capacitance wire (makes Kimber's look tame in comparison in that respect), but it's simply a great match with the F10.
