Lamm L2.1 Reference preampVladimir Lamm’s ultra-high-end electronics have paired beautifully with Kharma loudspeakers at prior shows, and this time Lamm Industries debuted a newly updated L2.1 Reference line-level preamp and separate power supply ($22,790 for both chassis) in a chain of Lamm electronics in front of Kharma’s latest flagship Veyron EV2 speakers ($437,500). Cables in this room were from the TchernovCable Ultimate series. The new L2.1 (and L2.1 PS) linestage has been completely redesigned to lower the noise floor, and the power supply now uses larger capacitors. Right and left channel signals are fully separated, including the volume controls, which are costly 40-stepped attenuators made in Japan. Lamm’s Signature tube electronics also delivered fantastic sound in a second room driving Kharma’s Exquisite Midi Grand speakers ($200k) in a demo that got better and better as the show went on.
