hi5.
Your Leben amplifier has an excellent reputation and I imagine that it's a very good match with the Zu speakers. These 2 amplifiers are fundamentally different designs . Push pull 6l6GC/el 34 compared to 845 (with 300b driver) SET,yep,they're different. Individual taste rules so hard to predict which one you'd choose. Given your music genre preferences the 845 SET would be a superb option. My bias is in the direction of the LM 219ia.
