Hey Tommy! I'm a Rogue Audio dealer, so will try to help as much as I can. Have you sent Mark/Nick an email at Rogue? They are generally pretty straightforward and helpful with items like this.
Most of the upgrades I've seen in the past involved amps. I don't remember ever sending a Metis in for the upgrade (and I don't remember what specific changes take place with the Metis). Preamp changes with them usually involve power supply, cap and diode upgrades.
The Metis is a fun pre. I imagine the upgrade would be a nice one for you.
