LAMM LP2 Phono


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. 

Tube Complement:
V101 -6C3P / 6C3П, left channel, first amplification stage;
V102 – 6C3P / 6C3П, right channel, first amplification stage;
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…

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.
