Durob Audio Mystere pa21 Stereo KT88 EL34 Tube 55 Watt Power Amplifier
Durob Audio is a company in the Netherlands that markets PrimaLuna tubed audio components, including integrated amplifiers, power amplifiers, and a CD player that has a tube-based clock. It also has discrete output stage with triodes running in pure Class A. Conventional CD players use op-amps in the output stage. Although the tube output stage and op-amp output stage sound different, one doesn’t necessarily sound “better” than the other, although tubeophiles would all opt for the “better”.
With the introduction of Durob Audio’s Mysterè line, we now review the Mysterè pa21, which is a 55 watt per channel stereo tube power amplifier. The Mysterè line goes beyond the PrimaLuna line with larger transformers, more power supply capacitance, and an auto-bias circuit that lets the consumer choose between using KT88’s or EL34’s as the output tubes. Trying different tubes is one of the things that makes tube products fun, and those who participate in this activity are called “tube rollers”.
Tube amplifiers have made their comeback, and if you are a “Retro” kind of person, or just someone looking to go back to a full-bodied tube sound, the Mysterè pa21 is your kind of product. It’s beautiful to look at the soft glow of the filaments in the evening adds to that peaceful sensation, reasonably priced, and delivers everything you might expect and desire from a tube amplifier.
