Hegel H20 Stereo Power Amplifier

David Levitan — Fri, 17 Nov 2023 01:45:09 +0000

The Hegel H20 incorporates the latest version of the Hegel FET-technology. A practical benefit of the H20 FET-technology is a more rhythmic sound. It is simply better at re-creating a bass line. Another vital element is the removal of harmonic echoes in the higher frequencies, which result in a lot more detail and still a smoother and more natural sound.

The core design of the H20 is based on the H30 reference amplifier, with the best possible implementation of our patented and laser trimmed SoundEngine modules. Also designed in the timeless Hegel look, it will fit in any modern or classic home. Just one single button on the front and a solid bead blasted and anodized front panel. A truly rigid design with well over 1,5 kg of aluminum in the front panel alone.

New too the H20 is bead blasted and anodized top and side covers. This adds to the exclusive look, and the overall design is more consistent. The Hegel H20 is a remarkable power amplifier with power capabilities of more than 130 Ampere. Extremely low distortion levels. Amongst the highest damping factor in the industry, and full control of the loudspeakers. All this to give you the most natural, rhythmic and dynamic sound on the market today.

Rogue Audio DragoN Stereo Power Amplifier

admin — Wed, 30 Aug 2023 23:37:09 +0000

Imagine a new kind of amplifier that combines the best of both the solid state and tube technologies. An energy efficient “green” design requiring no tube biasing or regular maintenance. An amplifier having the smooth and organic sound that only tubes can provide combined with the dynamics and slam of the solid state. Such an amplifier now exists! Critics are already using words like “Groundbreaking” and “Revolutionary” to describe our new tube/Class D hybrid amplifiers.

These new amplifiers are much more than simply a tube circuit placed in front of a class D output section. Our proprietary tubeD circuit topology actually integrates the tube section into the amplifier yielding the smooth natural sound that only a tube amp can provide. With almost uncanny accuracy the Dragon and Hydra amps deliver stunning dynamics and transparency without any of the edgy, etched or grainy sound that often accompanies solid state designs. A low power standby mode allows critical amplifier sections to remain continuously powered on (if desired) and a slow start feature allows the tubes to warm up gradually to eliminate turn-on noise and greatly extend tube life. Three massive linear power supplies are used to power the amplifier circuitry and ultra-high quality parts are used exclusively throughout the design. Combined with a stunning appearance, you can be certain that you are investing in an amplifier that truly represents the very leading edge of audio technology.
