Lamm Industries LP 2.1:
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 transformer ($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.” (Vol.38 No.3)
