CH Precision L10

TWO-CHASSIS LINE PREAMPLIFIER

Stereophile strives to distribute the wealth equally. Did that get your attention? What the statement refers to, in terminology devoid of dollar signs, is that Stereophile attempts to review products from different companies rather than repeatedly focus on products from a single company. We may consecutively review an amplifier and its companion preamp or preamp/DAC/ streamer, but I doubt we've ever reviewed three of a company's top-level products in six months. Until now.

Only a hermit, living remotely without access to media, need be told that we live in challenging times. Challenging times demand flexibility. After I experienced two consecutive product review cancellations-the first because tariffs forced the distributor to rebudget, the second because the product was not yet ready-Editor Jim Austin started reaching out Kevin Wolff, director of global sales for CH Precision of Switzerland, jumped into the breach, offering two of CH's reference products for review: the two-box version of the L10 line preamplifier ($80,500; $85,500 for premium finishes) and, for the following month, the two-much-larger-box M10 monoblock power amplifier. Together with Jim Austin's review of the CH Precision C10 D/A processor, that amounts to three reviews of top-level CH Precision products between October 2025 and March 2026.

Another compelling reason to move forward with these CH Precision reviews: Wolff is based in the Seattle area, southeast of Port Townsend and the Olympic Peninsula-in other words, close. He was able to visit me several times to install the products, adjust settings, and conduct interviews, for which I am eternally grateful. Thanks to him, CH Precision VP of Marketing John Giolas, and Jim Austin, I've been able to get a grip on the sound CH Precision strives to deliver.

Those two boxes
