What preamp for Lamm M1.2 ?

I never did hear the LL2. At the time, I wanted the best so I assumed the LL2 was not it. Based on Rcprince's description, it sounds like a pretty nice pre plus you can likely get further gains by tube rolling. You may also consider changing the 6922 in your amp as well, it responds quite nicely so tube choice is important.

If your L2 sounded muddy and dark, I suspect the power supply tube needs replacement or adjustment. The voltage setting can deviate quite easily particularly with an old tube causing the sound to be off. Read your owner's manual for directions. When the L2 is working properly, it is quite neutral and transparent.

Elberoth2, for what it's worth, I was in your situation 6 months ago looking for a great preamp and the best I found was the Lamm L2. As you mentioned, it doesn't have a remote and worse, the power supply tube often needs replacement and/or adjustment. If you can get over these issues, it's a good choice. There is something very right about this combo, tonality, transparency, and speed. It's just about perfect but if there's a flaw, it's a little mechanical sounding, at least to my ears.
