Cool array of gear my man! I've managed to keep my GAS problem in check my not reading up on new gear and staying away from posts like this.... but I had to read up on the Triple Rec!
Seeing as you have a lot of high end gear you may as well go high end to get the tones into your pc/mac. Two nice mics, a good preamp and a nice DAW mixer (Tascam or Mackie) with pro soundcard would give you pristine quality. Think Cubase SX4 or Nuendo for pc or ProTools for Mac.
Just looking at my own set up and you are making me jealous!
