The LL2.1 has a topology that provides the most natural sound in an audio channel using pure Class A operation from input to output; all cascades are single-circuit. The preamp's sound-neutral power supply is equipped with a full-wave vacuum rectifier.
The L2.1 Reference is based on a Class A circuit from input to output without general negative feedback. All cascades, including the high—voltage output, are single-cycle. Selected high-voltage transistors (MOSFETs) are used in the signal path, and the volume control is implemented on a high-quality TKD step potentiometer (Tokyo Ko-on Denpa).
The 1.1 Signature monaural line-level preamp is a direct replacement for the L1 Signature, which since its introduction in 2010 has become the absolute benchmark of excellence among LAMM line-level preamps. The signature L L 1.1 proudly continues this tradition.
