I was planning on upgrading my Presonus Firebox to a Firepod in the near future to get more inputs, inserts, and what not...But now I've had a resurgence of good hope in my little Wunderkasten. I've only been using the 2 mic preamps built in the box, and occasionally will use the line-ins w/ bass pre's and what not. I've never tapped into the SPDIF breakout before, but knowing that I can get an additional 2 channels from that, do any of you have recommendations on a sub $400 dual-channel preamp? Nothing with 'added color', just something simple and clean, but hopefully not sterile. I'm thinking of using my 2 line-ins for the 'colored' pres, the built in pres and SPDIF pres for general mic'ing. Perhaps there's a Presonus unit or something with a similar build to my existing built in pre's that would work well here? Anyone?
