About the Hyperion

Hyperion is a high-power hybrid monoblock amplifier that takes the technologies Ypsilon has developed over the years to the extreme.

It combines high output power with no overall feedback and a simple, pure signal path of only two gain stages, delivering more than 370 W into 8 Ω and 1150 W into 2 Ω.

The first gain stage uses a low-impedance double triode, coupled to the output stage by a wide-bandwidth silver interstage transformer. A specially made silver input transformer provides a perfectly balanced input.

Its 'balanced single-ended' output stage is biased in class A up to 100 W into 8 Ω, blending effortless drive and dynamics with the refinement and transparency of a pure single-ended design. The power supply is built around large inductors and multiple fast capacitors, and all internal wiring is Ypsilon's own Teflon-insulated silver wire.

Highlights

  • Two gain stages, no overall feedback
  • Silver input and interstage transformers
  • 'Balanced single-ended' output stage, class A up to 100 W @ 8 Ω
  • Ypsilon's own silver wire throughout
