Which tubes perform best in Fezz amplifiers?
With Fezz Audio, the device families should be clearly distinguished: Mira Ceti and Lybra 300B represent the 300B world, Silver Luna and Luna Mini stand for EL34, Titania for KT88 and Olympia for the more powerful double-mono concepts. In addition, units such as Alfa Lupi, Omega Lupi or Sagita expand the range upward and into special areas. Our earlier assessment therefore referred only to the 300B models and not generally to all Fezz amplifiers. For Mira Ceti 300B and Lybra 300B, we looked at the topic more intensively: very high on our list is the Linlai WE300B, because sonically it moves in the direction of the great American original, musical, pleasant and with a beautiful soundstage. Also very strong is the Linlai 300B-D Dream Series with high resolution, clean bass and plenty of dynamics. The Genalex Gold Lion 300B is a very good all-round tube with a rather warm tuning, and the JJ 300B does a lot right for its price level with a tight, fast playing style. With Silver Luna or Luna Mini, however, the EL34 is the focus, and with Titania the KT88. Many suitable tubes for Fezz Audio are available from BTB in selected quality, with power tubes also available on request as matched pairs and quartets, as well as suitable upgrade solutions for the preamp tubes.
