One thought on “Ken-Rad 6SN7GT/VT-231 Clear Glass”
Despite extensive debate within the audiophile community regarding the sonic merits of Black Glass versus Clear Glass variants, empirical testing suggests there is no discernible acoustic difference between these two versions of the Ken-Rad 6SN7 vacuum tube.
Key Findings: Acoustic Transparency: In comparative listening tests conducted across multiple amplification systems, the sonic signatures remained identical.
Structural Consistency: The internal architecture appears consistent across both glass types, suggesting that the “Black Glass” coating (carbonized nickel) is a manufacturing variation rather than a performance-altering design change.
Conclusion: Listeners seeking the legendary “Ken-Rad sound”—characterized by its robust bass and rich midrange—will find both versions perform to the same high standard.
