Sound Sample:

Soundlumia's Opinion
The most distinctive sound feature of the Heerlen ECC82's is the transparent, natural and expansive midrange presentation, with a slight touch of warmth that illuminates your music. Every piece of music you play through these tubes sounds like from a vinyl record, whether your sound source is phono or not. The sound stage is spacious, deep and structured. Bass is incredibly deep but well controlled and feels as accurate as on the high end German ECC82's (Siemens, Telefunken, Valvo etc.)  We would recommend these as an excellent alternative if you are seeking the high end Holland ECC82 tubes that can deliver the legendary Philips house sound flawlessly.
