2x Amperex Holland 6922 = E88CC w/ One Select Tube - Heerlen 1964/65 - NOS

Product Summary The "textbook Heerlen sound" has been referenced in several Soundlumia E88CC listings, and many tube enthusiasts asked what all that means. So here 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 Holland 6922 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 super high-end German E88CC and CCa tubes.  Professional Sound Evaluation
