I believe the Mc2102 has a level control for the amps input?
Haven't auditioned one in a few years so I dont remember if it did, but I'm gonna say you will be very very happy with the results of the Lamm/Mc2102 combo.
The 2102 is a really sweet amp and very elegant in looks and sound If I didnt come across my Mc-3500's I was considering a pair of 2102's and running them in mono.
The Lamm pre is a very tight and crisp sounding pre with great bass out of the box. The 2102 is a warm sounding amp and the combination would work well together.
