LL2 Deluxe

About the LL2 Deluxe

The Lamm Industries LL2 Deluxe is a vacuum tube line-level stereo preamplifier designed for audiophiles seeking natural and highly transparent sound reproduction. It operates in pure Class A, single-ended topology from input to output, employing a full-wave vacuum rectifier and choke-filtered power supply to minimize hum and buzz, ensuring a wide dynamic range without coloration. The Deluxe version features approximately double the power supply energy storage compared to the standard model, with additional polystyrene capacitors paralleling film capacitors in critical signal paths, resulting in greater dynamics and improved handling of sudden power demands. It includes three inputs (Line 1, Line 2, and Direct), one tape loop, two sets of outputs, a front panel mute switch, and protection circuitry with automatic mute at power on/off. The Direct input bypasses some switching for a purer signal path. The preamplifier is hand-crafted with high-quality components such as military-grade low noise DALE metal film resistors, ALPS stepped attenuators, ELECTROCUBE and ROEDERSTEIN film capacitors, and Cornell Dubilier electrolytic capacitors. It uses tubes including two 12AU7A, two 6DJ8, and one 6X4 for rectification. The chassis measures 19.25" W x 5" H x 13.75" D and weighs 20 lbs. The LL2 Deluxe is known for its almost inaudible sonic signature and ability to recreate a three-dimensional soundstage without boundaries, especially when paired with Lamm power amplifiers.
