Cyber 100 15th anniversary special edition !

If Opera audio has ever offered a special anniversary line of equipment with a coherent design philosophy, it would be the 15-year-old M100 series push-pull integrated amplifiers. Opera Audio has centered its philosophy on highly over-specified massive output transformers, which are entirely hand-wound at the factory. These transformers are in fact output transformers with a non-symmetry configuration. Power pentodes like the KT88, 6550, 6CA7, KT77 and EL34, are configured to function and sound like single-ended triodes with the advantage of considerably increased output.
The whole M100 series line has been built around this concept. From M100, M100MKII, M100SE, M100plus to the Cyber 100 signature, they were gradually making their mark, slowly improving their design's most glaring faults, one unit at a time, and yet - the critics could not deny the utter musicality and the extraordinary presence.

Stepping into 2008, Opera audio and our satisfied M100 users, including most of our long time distributors, worked together to develop a 15th anniversary amplifier that would completely conform to the special concept of what a push-pull pentode integrated amp should sound like.

The pursuit of the Cyber100-15 th anniversary edition is music purity and the most natural reproduction of sound in an affordable integrated amp that can possibly be achieved. This amp has a superb and enchanting midrange, the result of the harmonic balance that Opera Audio has always strived for and possesses an extraordinarily smooth balance throughout the spectrum, providing a stronger impression of live music. The exterior of the previous Cyber 100 signature has been modified with an aluminium top cage, walnut wood deck and a 15th anniversary logo.
