The LL2.1 is a preamplifier from Lamm Industries, sharing the LP2.1 Phono's chassis dimensions with an exceptionally wide bandwidth. The LL2.1 brings Lamm's considered engineering to dedicated line-level signal control.
Key specs that matter
Three single-ended inputs are provided, with two single-ended outputs. Input impedance is 50,000 ohms single-ended. Frequency response spans an exceptionally wide 1.5Hz to 400,000Hz within plus-or-minus 3dB - a remarkable range extending far beyond audible limits. Total harmonic distortion plus noise is 0.03%. At 11.4 x 48.2 x 35.2mm and 9.1kg, the LL2.1 shares the LP2.1 Phono's chassis footprint with somewhat less mass.
Sound and use context
Expect a distinctive hybrid character combining tube-stage warmth with solid-state precision, with the exceptionally wide 1.5Hz-400kHz bandwidth reflecting Lamm's uncompromising engineering philosophy.
Pairing
Lamm's own LP2.1 Phono offers a natural, brand-coherent pairing within the same broader catalogue.
Alternatives
Other manufacturers' comparable hybrid tube-and-solid-state preamplifiers offer alternatives for buyers wanting to compare features at a similar price point.
