Oneobgyn, your poor experience with the L2 was unfortunately my fault. One of the XLRs I brought over and had been using turned out to be faulty causing a significant compromise to the sound. When we listened to your Ref 3, Vahallas were used bypassing this problem. Consequently, I dont think your experience with the L2 was accurate.
A few weeks ago, I had a Ref 3 to compare in my system and to me, the L2 was superior. The Lamm was more natural and transparent with a lower noise floor. I felt like it was more pure while the Ref 3 had a slight agenda. The differences were not drastic, as expected with components at this level, but evident under critical listening.
