The ML2.1 is one of the best (true, no coloration) sounding Amp available. But, the bring the best out of it you need a Speaker which is not a "black hole" from the crossover/Chassis.
The M1.2 is imo the next best for the User with a regular sensitive Speaker.
My experience with LL2 Preamp
Unbelievable good. From Performance and Price. Clear in Tone, superb Soundstage, no smeared detail and when you hear voices with the LP2 as source, it is the real thing.
The L2R is a bit better in the higher frequencies, based on better parts, but it has not the Magic from the LL2
