The LL2.1 features the following upgrades and modifications as compared to the LL2:I see only items 3 and 5 possibly changing things sonically, and I doubt the changes are dramatic, or they would have listed them in more detail. The caps appear the same. I would liked to have seen stepped attenuators. The more significant changes appear to be the remote on/off for Lamm amps, and the 15db attenuation switch. They were recently very helpful in helping me set up a remote on/off for my M1.1 amps. Lamm uses a high quality relay for that purpose and the remote does not even have to be hooked to a power supply, it must simply complete a circuit when the back power switch is in the "remote" position - it was very easy. They have reviews of the new LL2.1 coming up in Stereophile, The Absolute Sound and Soundstage, so we will be hearing a lot about it.
