My friend is looking for amplifier recommendations for the Jubilee bass bins. He has been using a 2A3 for the horns, McIntosh for the bass bins and a pair of Behringer EP4000 for the BassMaxx sub horns. You could say he likes dynamic and concert level sound. He now wants to try a pair of solid state monoblocks for the bass bins and use the McIntosh just as a pre. I was thinking maybe Emotiva XPA-1, D-Sonic M3-1500M, Red Dragon M1000, or possibly an Adcom GFA-5802. What do you think would work with this rig?
