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.

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…

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.
