CH Precision
L10 Stereo
Introduced 2021$85,500 MSRP
The flagship of CH Precision's Swiss-built 10 Series, the L10 is a dual-chassis line preamplifier pairing a fully discrete, fully balanced analog signal path with a current-domain R-2R ladder volume control, and it can be expanded from stereo dual-mono into a full four-chassis true-monaural array by adding a second unit. Reviewers have praised its exceptionally low noise floor and vast dynamic range, with *Stereophile*'s John Atkinson calling its measured performance some of the best he has tested (The Absolute Sound).
