I had a pair of Rogue M-120's and had mated them with an AI Mod 3a. It was a superb combination. I haven't heard the Mod 3 but I understand it was a bit darker sounding than the Mod 3a. My Rogue's originally had Sovtek KT-88 power tubes and they sounded a bit bright and harsh with the Mod 3a so I swapped out the KT-88's for some 6550's which was a significant improvement. I'm thinking that KT-88 power tubes in the Rogue amps might be just the ticket for the darker sounding Mod 3.
