Quotes:
“"Like a warm British jacket of the finest tweed, theseglorious tubes have an attractive sweet warmth in their midrange and lowerregions. The top end is silky and pleasant, without being rolled-off. The bestof these tubes retain a fine sense of "air" at the top, and the uppermidrange is smooth and liquid. These tubes reproduce the human voice,especially female voices, with haunting realism." – Brent Jessee
