Having owned both the 300.1 and Lamm Ref 1.2 and ML1 I can tell you the Ref 2.1 would be my last choice. Both the 300.1 and the ML1 are much better then the Ref 1.2. I think the Ref 1.2 are underpowered and just didn't sound right. Both the 300.1 and the ML1 are very natural and very powerful given there ratings. 300.1 has a lot of gain so preamp matching is important.
