ML3 Signature

About the ML3 Signature

The Lamm ML3 Signature is a no-compromise, single-ended (SE) tube monoblock amplifier featuring a very powerful direct-heated triode GM-70 with 125W plate dissipation. It produces 32 watts continuous output into 4, 8, or 16 ohms in pure class A operation without overall feedback. The amplifier uses a sophisticated separate power supply chassis and custom-made output transformers to ensure wide bandwidth and exceptional sonic performance across the entire audible frequency spectrum, including deep bass and extended highs. It includes multi-turn trimming potentiometers for precise plate current adjustment and offers both XLR and RCA inputs. The ML3 Signature is renowned for its extraordinary transparency, three-dimensional soundstage, and ability to recreate music with astonishing realism and naturalness, making it one of the finest single-ended tube amplifiers available. It weighs approximately 79 lbs for the amplifier chassis and 80 lbs for the power supply chassis, each measuring 15.8" W x 8.2" H x 20.2" D. The amplifier has received high praise from audiophile publications such as Stereophile and SoundStage, and is considered a benchmark in tube amplification.
