Lamm Industries has been a venerable brand name in high end audio for decades. They build each product when it is ordered, so you won't see a bunch of any particular model "in stock" anywhere. Their specialty is tube-based preamplifiers and power amplifiers, with their top-of-the-line power amplifier selling at well over $100,000. The current review focuses on the model LL2.1 stereo preamplifier. At $5,990, it is the most affordable preamplifier in the Lamm product line.
