Soundlumia's Opinion
This is not a listing about audio tubes but an invitation for you to hear the sweetest voice on Earth. No other tubes can deliver vocals like the British made audio valves, whether they're from Mitcham, Blackburn or Rochester, and that's a fact.
The overall tonality of British made E88CC tubes is warm and lively with a very spacious sound stage. "Like a warm British jacket of the finest tweed, these glorious tubes have an attractive sweet warmth in their midrange and lower regions." This is how the experts on audiotubes.com describe the sound signature of these wonderful tubes. The top end is silky and pleasant and doesn't get rolled off. They retain a fine sense of "air" at the top, and the upper midrange is smooth and liquid. These tubes reproduce the human voice, especially female voices, with haunting realism. The y are also known to have an attractive sparkle at the top with rich bass...now we know where that "warm British jacket" comes from!
