Note: Specific numeric figures vary slightly based on regional/model variants (e.g., versions using EL34 vs KT88/6550 power tubes). Leben typically does not publish exhaustive modern data sheets; much of the specification above is drawn from owner manuals, lab measurements and widely referenced user/test data.
Resources & Reviews
-
Hi-Fi World / Reviewer Summaries: Reviewers consistently note the CS-600’s integrated musicality and smooth, engaging midrange — with especially natural timbre for vocals and acoustic instruments. It’s widely appreciated for its ability to “draw you into the music” rather than presenting cold, analytical measurements.
-
Stereophile / Community Feedback: While seldom reviewed in major western press, community and audiophile forum threads highlight the CS-600’s excellent soundstage, harmonic richness, and relaxed treble — traits many tube lovers seek. Some owners point out that the CS-600 pairs particularly well with floor-standing or efficient stand-mount speakers.
-
Owner Reports: Tube-enthusiast users often describe upgrades (e.g., coupling capacitor swaps, tube rolling) as yielding notable changes in personality — which speaks to the CS-600’s tweakability and classic tube design ethos.
