Finally, after weeks of bumping around the internet I managed to find Achilles Tires for the front (235-40-18) and rear (275-30-19) of my '04 Coupé. I picked up my Crossfire from the tire shop today and have to say these tires are, without a doubt, the quietest tires I've had on the car. I'll love 'em for that reason if no other. Five miles isn't enough of a run to give any sort of a test report, but as soon as I've run a couple of hundred miles, I'll post an update.
