Ypsilon Hyperion

Mono Block Hybrid Power Amplifier

The Hyperion is a high power hybrid monoblock amplifier which takes the technologies that Ypsilon has developed for its power amplifiers to a new extreme.

The Hyperion combines high power output with no overall feedback and a simple and pure signal path of only two gain stages . It outputs more than 370W @ 8 Ohms & 1150W @ 2 Ohms.

The first gain stage uses a low impedance double triode coupled to the output stage with a wide bandwidth silver inter-stage transformer. The amplifier can accept the high transconductance 6H30 or 5687 types. Core performance of the amplifier is maintained with either type.

Its unique ‘balanced-single-ended’ output stage biased in Class A for 100W @ 8 Ohms achieves an unmatched blend of effortless drive and dynamics with the refinement and transparency of a pure single-ended design.

The Hyperion’s power supply is based on large inductors for smooth filtering and multiple fast capacitors. The power supply transformer is built with high quality core material and winding techniques for ultra-low mechanical, magnetic and electrical noise.

All internal wiring is with Ypsilon’s special silver wire with teflon insulation. Sophisticated protection circuits ensure a reliable operation regardless of connected load. The silver input transformer provides a true balanced input and in combination with two ground lift switches makes the amplifier easy to adapt in different grounding conditions.

Many experienced audiophiles have considered the ‘Holy Grail’ of power amplification to be an amplifier that can produce the delicacy, transparency, tone and realism of a single ended design but with real world power output that can drive virtually any modern loudspeaker. Until now, this has been attempted but without ideal results. The Hyperion not only achieves this ideal, but it has set a whole new standard that was until recently, considered impossible. Considered by many in the world’s audio press to be an absolute game changer, the Ypsilon Hyperion is now used as the power amplifier of choice in many of the world’s reference systems.

Stereophile, Michael Fremer, 2018

When you make your living by listening to audio gear, at some point you inevitably suffer burnout. While I can’t live for long without hearing music in my listening room, there are times when I crave silence to avoid such a burnout. But during the time the Hyperions were here, I think I did more listening for pleasure alone than I’ve done in years. If you’ve got the money, I wholeheartedly recommend the Ypsilon Hyperion. It’s among the handful of the best-sounding power amplifiers I’ve heard, and it’s the most musically enjoyable of the lot.

I’d rather that a component err on the side of musicality, bliss, and all the other things that can gently propel you into a meditative state when listening to your system. The Hyperion does this. There are other amps that will play even louder or go deeper in the bass or provide even greater grip on the notes. But the whole package that the Hyperion offers makes it quite irresistible. So if you’ll permit me a little hyperbole—and since when has that ever figured in the high end?—I’d say that Demetris Baklavas has produced something worthy of the Greek gods. If you’re currently resting in base camp on your audio journey and looking for a proper ascent, then the Hyperion may allow you to steal a march on the path that leads to that elusive sonic Mount Olympus.
