The Absolute Sound gives the 2018 Editor’s Choice Award to these products (issue 281, March 2018):

ML3 Signature amplifier
This four-chassis, 32Wpc SET amplifier sets new standards in sound reproduction. The ML3 delivers amazing speed plus captures the full harmonic envelope of each instrument. The result is unparalleled tonal neutrality. Surprising, for an SET design, the Lamm can be used with a wide range of loudspeakers, though care must be exercised in impedance and sensitivity matching. (reviewed by Peter Breuninger, issue 208, 2010)

ML2.2 single-ended amplifier
This 18W single-ended triode amplifier from Vladimir Lamm defies all the stereotypes about SET amplifiers. The ML2.2 doesn’t offer a glorious midrange at the expense of the frequency extremes; it offers a glorious midrange in addition to glorious performance over the entire spectrum, save for the lowest bass. Simply put, the ML2.2 sounds more realistic — more like live instruments — than any amplifier RH has heard. The caveat is that you must mate the ML2.2 with a loudspeaker of high sensitivity and a benign load. (reviewed by Robert Harley, issue 230, 2013)

M1.2 Reference amplifier
Another winner from the fertile mind of Vladimir Lamm.  Combining brawn and finesse, the M1.2 drives even challenging loads with ease.  Its siren song of suave harmonic textures, tight bass control, articulate transients, kinetic drive, and essential tonal neutrality is musically most persuasive. (reviewed by Disk Olsher, issue 188)

LL1.1 Signature preamplifier
This four-chassis, dual-mono preamplifier is that rare breed that strikes a near-perfect balance between transient attack and instrumental body, and does so from top to bottom in both frequency response and amplitude. Its ability to deliver speed plus sustain at all dynamic levels is extraordinary. The result, said reviewer PB, is near-perfect timbre and, if the rest of your system is up to it, nearly ideal imaging. (reviewed by Peter Breuninger, issue 208, 2010)

LP2.1 phono preamplifier
A significant upgrade of the LP2, which was Lamm Audio’s entry-level phonostage for many years. The emphasis is entirely n signal purity. An exceedingly low noise floor is a major plus, allowing the music to swell up from a velvety black background with no perceptible hash or grain. The presentation is detailed, but not overly so. The vibrancy and urgency of human voice are reproduced exceedingly well. Tonal colors are beautifully rendered but without excessive tube warmth. The tonal balance is very much on the neutral side of reality. Inn sum, a perfect marriage of traditional solid-state strengths with the harmonic textures of tubes. (reviewed by Disk Olsher, issue 248, 2014)

L2.1 Reference line-level preamplifier
The L2.1 Reference is a hybrid design but not in the usual sense. The power supply is all tube while the audio circuit is solid-state. MOSFETs are used in Class A, no-feedback circuitry fr the gain and buffer stages. Sonically, the L2.1 is clearly deserving of the “Reference” appellation, holding up as it does a mirror to the music. It cuts through previous limitations of solid-state preamplification allowing the music to flow with precision and emotional conviction. (reviewed by Disk Olsher, issue 278, 2017)

LL2.1 line-level preamplifier
This all-tube linestage preamp (with tube rectification) captures 80% of price-no-object preamps for a fraction of their cost, said our reviewer DO. Never in-your-face analytical, the LL2.1 frames details organically within the fabric of the music. Treble, bass, and transparency can be improved by using the right after-market tubes. (reviewed by Disk Olsher, issue 198, 2009)

STEREOPHILE
The following products appear in STEREOPHILE’S Recommended Components lists (April 2018, Vol. 41, 4):

M1.2 Reference amplifier
The 110W M1.2 with tube front end and MOSFET output stage, comprehensive short-circuit protection, and high/low impedance settings, offered “unflinching honesty in conveying the true nature of the music that passed through it,” said PB. “Utterly continuous and coherent from top to bottom,” the M1.2 combined resolution and transparency with harmonic completeness, timbral richness, and glow. [The sound]…impressed JA with its three-dimensional soundstaging and midrange richness. “This is a great amplifier,” JA decided. “High recommended.”

L2.1 Reference preamp
” The greatest accomplishments of Vladimir Lamm’s electronics are like those of the art restorer who removes grime and soot without diminishing the vibrant colors underneath—so believes AD, who said of Lamm’s latest line stage, the two-box L2.1 Reference, “[it] reproduced the sounds of bowed and plucked strings alike with color, texture, and humanness.” The Lamm does so with an unorthodox combination of technologies: high-voltage MOSFETs in the all–single-ended gain stages, and tubes throughout its power supply—for rectification, regulation, and the amplification of voltage references. The L2.1 Reference, which differs from its predecessor in its use of new current-source transistors and other recently available components, offers switchable signal-phase inversion and easily adjusted channel balance—the latter thanks to its dual-mono volume potentiometers—and further delighted AD by eschewing remote control. His verdict: “the rare product that swept the question of tubes vs solid-state into insignificance.” Writing from his test bench, JA noted the Lamm’s “extraordinarily low” distortion and observed that, “like the other preamplifiers designed by Vladimir Lamm that have passed through my test lab, the L2.1 Reference is well engineered.”

LP2.1 phono preamp
The LP2.1 Deluxe – the adjective refers to this version’s upgraded power supply, polystyrene bypass caps, and 20.5-lb damping panel — is a single-box stereo phono preamp with tube rectification and pairs of Russian-made 6C3P and 6C45P-E triode tubes for the signal path. The dual-mono design has separate, switchable RCA-jack inputs for MM and MC cartridges, the latter of which address a pair of Jensen 1:10 step-up transformers for additional gain. Controls are minimal, with no provisions for varying the 400-Ohm load of the MC inputs — although, as MF observed, that figure is “a good compromise for cartridges with internal impedances of about 40 Ohms or less.” MF found the “smooth-sounding, well-detailed” LP2.1 to be remarkably free from noise — even quieter than some solid-state phono preamps — and observed that “the sound of MCs through the LP2.1’s transformers was impressively fast, detailed, open, dynamic, and resolving — all without added glare, grain, or etch.” At the same time, he was even more impressed when preceding the Lamm’s MM stage with the Ypsilon MC-10L step-up transformers ($6000), which “seriously upped the sound quality along with the price.” Still, MF considers LP2.1 Deluxe “fully competitive with anything at or near that price.”
