Product Description

Integrated Amp with remote, JJKT88 push-pull, 35W

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 in-house. 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 satisfied M100 users,  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 Cyber 100 15th 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.

Self-biasing KT88/ 6550 works at Class A, UL operation, with a well designed NOS 5687 drive stage and a time–proven rectifier circuit consisted of the 5AR4 EH rectifier tubes and Philips electrolytic capacitors (for audio). Every component chosen has been carefully selected for better audio clarity, that even goes for the German made power switch. After all the KT88/6550s aren't triodes but, if properly applied as such in a circuit with 35 push-pull watt output, they can exhibit surprisingly good linearity, steady performance and approaching that of the real thing – something you'd expect from triode units running single-ended and powerful enough as well.
