Soundlumia's Opinion

Stronger than time! This is the classic beauty in sound, admired by audiophiles for more than 50 years and will still be our top choice in the next 50 years. The legendary Siemens tone is considered the "reference sound" for serious classical listeners who need to upgrade the sound quality at phono stage. 

The airy and transparent sound produced by these vintage Siemens tubes has been unrivaled even to this day. The magically extended yet never tizzy highs, coupled with the slightly focused upper mid-range, deliver a clear presentation of the entire frequency spectrum, completed by the precise and deep controlled bass. And the most defining sound characteristic of Siemens E188CC tubes is their ability to retrieve the deepest levels of detail in sound, and these hidden sonic layers can go a long way to revealing the subtle ambient clues that help complete building a truly 3D holographic presentation. While as quiet and analytical as the best Telefunken E188CC tubes, Siemens E88CC's produce a warmer, smoother and more musical sound. To see how they compare to each other, please also see Soundlumia's exclusive Telefunken E188CC listings.
