The Evolution One is a high-end single-ended Class A amplifier delivering 2x4W using 2A3 EH gold grid tubes. Featuring Double-C core transformers, no negative feedback, and meticulous component selection, it offers refined sound for high-sensitivity speakers with an elegant wood and metal design.
The Evolution One is one of the finest products in its class. Single Ended topology, no-negative feedback, Double-C core output transformers and top-notch power supply are just some of the ambitious specifications that Trafomatic Audio established as a de-facto standard for their amplifiers. With its design and sound quality the Evolution One will represent an easily recognizable style. It will bring a new dimension to your listening pleasures.
Check out why!
Balanced wood and metal elements give the Evolution One very attractive appearance with dominant elegant and modern look, positioning the whole Evolution series at the top of the world class products.
High quality output transformers built around Double-C geometry and 220VA EI M6 power transformer dominate the top plate of the amplifier. Oversized filter chokes inside underline quality construction throughout the unit. Vacuum tube rectifiers go without mentioning: direct heated rectifier 5U4G occupies central position in the tube lineup. Driver tubes are ECC81 coupled to the output stage via Solen fast capacitors. Power stage consists of two 2A3 EH gold grid tubes (one per channel). This specific variety has been chosen for increased dissipation capability and better musicality due to reduced third harmonic distortion.
Output power is 4W, therefore higher sensitivity speakers are recommended (95dB or higher). Gold plated robust input and output terminals are standard on every Evolution One amplifier.
The amplifier is available for every input voltage option (100-120-220-230-240Vac) and is equipped with standard IEC connector.
ALPS volume control, Solen coupling capacitors, high reliability Aluminum Electrolytic capacitors and other quality parts ensure that sound quality is maintained throughout the amplifier’s life.
