The L2.1 is said to have evolved from the L2, for many years a mainstay in Lamm Audio’s product lineup. Evolution is generally regarded as inevitable but when starting with the nearly flawless circuitry of the L2 how do you progress to L2.1? Well, attenti...

Amplifier power output uses vacuum tube
Whether or not phase is inverted. Just swap speaker leads black for red if permanently inverted
Balanced architecture internally
A post to connect grounding wire to, often helpful for troublesome turntable setups
Number of seperate chassis to form a stereo 2-channel preamp
Note that some inputs may be either RCA or XLR, not both, so the total count of inputs is often less than just adding the RCA inputs to the number of XLR inputs
number of phono XLR inputs of any kind (mm or mc)
number of phono RCA inputs of any kind (mm or mc)
Output allows recording or equalization of source before it gets to the volumn control
Output allows recording or equalization of source before it gets to the volumn control
number of headphone jacks of any kind
Wall power consumed when playing at rated output
Has a built-in DAC (digital to analog converter)
Switchable or permanent low gain. Useful for horn speaker systems, for example. Normal gain preamps make these systems very loud even when the volume is turned to 1.
Total weight of all boxes required to make a stereo preamplifier
Also known as Unity Gain or processor bypass. Input allows home theater preamp to send front 2 channel signal through audio preamp, bypassing the audio preamp volume control, to the main speakers. This way only the HT volume control controls the volume of the entire HT system as well as preserving the quality of the HT signal by not having it have to go through the audio preamp's gain stage
Also known as a tape in/out loop. A combination output and input that allows a processor, like an equalizer, to processes the signal between the source, like a CD player, and the volume control.
Output impedance for single-ended output. Double this for balanced output
Maximum output voltage for single-ended output. Double this for balanced output.
Weight of all pieces and packaging
