Product Summary
The "textbook Heerlen sound" has been referenced in several Soundlumia listings of Amperex Holland E80CC/6085 tubes, and many tube enthusiasts asked what that all means. So this is the answer: the late 1950s and very early 1960s tone, the beginning of over a decade's excellence in sound, the classic tonal template for all the great (and greater) Amperex/Philips/Valvo/Miniwatt tubes to be made in the years to come, the timeless Philips radio tone that many of us grew up listening to.
Sound Qualities
The most distinctive sound feature of the Heerlen 6085'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, structured and holographical. Bass is incredibly deep but well controlled and feels as accurate as on the high end German E80CC's (Siemens, Telefunken, Valvo Hamburg etc.) The stellar performance of foil d-getter takes all these wonderful sound qualities to a whole new level: instrument separation is super clean, detail retrieval is surreal, and it goes without saying that the extremely low noise on these tubes is to the vanishing point.

The tube worked wonderfully and sounded terrific in our professional studio setup for monitoring.
