The Ypsilon Aelius II is a reference push-pull hybrid monoblock power amplifier engineered to deliver massive dynamic output, speaker control, and pure musical involvement. Its minimalist hybrid topology features only two gain stages with zero global feedback: a single-ended Class A vacuum tube input stage coupled directly to the output stage via a custom wide-bandwidth (10 Hz – 75 kHz) interstage transformer. The inclusion of a bespoke input transformer enables a fully balanced XLR signal path without adding active components. Its unique output stage utilizes same-polarity N-channel MOSFET components operating in a bridge-balanced symmetrical topology, supported by high-current inductor-filtered power supplies to deliver effortless current drive, ultra-low noise floor, and complete signal purity.

Ypsilon Electronics was established in 1995. It was founded by two sound engineers with extensive experience in the field of live music reproduction. It was not only their experience with live music and concerts that provided the necessary knowledge, but also their technical background in electronics; it was precisely this that helped shape their vision of how a high-end audio device should function and what level of reliability it should demonstrate. It was precisely their love of natural live music and their determination that compelled them to transform this passion into technology – technology that combines traditional approaches with modern, pioneering design solutions and processes. The result of these efforts is a range of unique products that convey the true essence of music to listeners… emotion!
