LP2.1 Phono Pre
LP2.1 Stereo Phono Preamplifier
The LP2.1 is a dual-mono vacuum tube phono preamplifier with two electrically and mechanically separated channels. It features a topology that brings out the most natural sound performance in the audio path, as well as graceful and sophisticated design.
All amplification stages utilize high transconductance very low noise high-current vacuum triodes. No loop feedback is employed.
The LP2.1 features a very accurate passive RIAA EQ network. The preamplifier’s audibly neutral power supply features a full-wave vacuum rectifier which, together with a choke-containing filter, helps reduce the hum and buzz to almost negligible levels and, in the end, ensures the verity of dynamic range without coloration. Solid-state analog voltage regulator is used as a heater supply. Other features include two sets of inputs for each channel and gain/selector switches for MM and MC cartridges.

V103 – 6C45P-E / 6C45П-E (original), left channel, second amplification stage;
V104 – 6C45P-E / 6C45П-E (original), right channel, second amplification stage;
V105 – 6X4, full wave voltage rectifier.
What Reviewer have said:
….Let me make this perfectly clear: the LP2 exceeds the standards set by its competitors, regardless of price or prestige. It is a unique product that blends together some of the traditional solid-state strengths of solid stage designs such as bass power and low-noise, with the glorious harmonic textures and dynamic conviction of tubes. The Lamm Industries LP2 makes a statement…

…”Very low noise floor”, “tremendous bass weight and definition,”, “magnificent midrange,” and “nicely extended treble”; has the ability “to define the physical layout of performers in the recording space” as well as “deliver realistic dynamic contrasts at both the micro and macro levels”; “the level of transparency…was second to none”. “Has the ability “to define the physical layout of performers in the recording space” as well as “deliver realistic dynamic contrasts at both the micro and macro levels”; “the level of transparency…was second to none.”
Although a relative latecomer to the analog party, the Lamm Industries LP2 offers truly extraordinary performance… With its benchmark-setting noise floor, explosive dynamics, see-through transparency, and superb extension at the frequency extremes, the LP2 should be on the proverbial short-list of anyone who’s looking for a phono stage at or well above its price range.
