The Phaethon is a truly unique high-end integrated amplifier, incorporating many of the core technologies developed for YPSILON’s acclaimed Aelius monoblocks and PST-100 MkII preamplifier—now distilled into a compact, elegant, and high-performance form factor.
This hybrid design features only three active gain stages, two of which are low-noise vacuum tubes operating in single-ended Class A, serving both the input and driver stages. This minimalist topology ensures refined sonic character and exceptional musicality.
Volume control is achieved through a handcrafted transformer-based attenuator, internally manufactured and ingeniously integrated into the preamplification section. Utilizing a post-attenuation technique, this approach maintains signal purity and avoids coloration.
The tube driver stage is coupled to the output stage via a wideband interstage transformer, which also provides highly accurate and balanced phase splitting.
The output stage features same-polarity semiconductors for both phases in a proprietary Single-Ended Balanced topology. This delivers the warmth, naturalness, and harmonic richness of single-ended designs, while also offering the grip and power typically associated with push-pull amplifiers.
Crucially, the first watts—those most critical to perceived sound quality—are delivered in pure Class A, resulting in exceptional musical involvement from the very first note.
The Phaethon employs independent power supplies for the tube and output stages, incorporating five filtering inductors. This ensures silent, stable operation with an ultra-low noise floor, allowing the music to emerge from a pitch-black background with stunning clarity and realism.
Full-function remote control.
High-visibility LCD display with large characters, readable from across the room.
Optimized three-stage gain architecture, including a vacuum tube preamp section.
Transparent, transformer-based volume control, handcrafted for purity.
Single-Ended Balanced Class A output for the all-important first watts.
The Phaethon is not just an integrated amplifier—it's a reference-level amplification platform, flawlessly merging the best of vacuum tube and solid-state design. It's the ideal solution for high-fidelity systems where space is at a premium, but no compromise in performance is acceptable.
