Heed Audio Thesis Gamma - Stereo Power Amplifier

Premium RC-coupled Stereo Power Amplifier

Representing a new discourse in the line, the Thesis γ (gamma) stereo power amplifier is arguably the most athletic member of the family. With great effort, Heed have succeeded to squeeze two Thesis-class Transcap module into one rather tiny, but chunky metal chassis. Its wall-to-wall transistor array supplies tremendous energy for two channels of music, without the slightest feeling of necessity. Perfect for those systems that perhaps can't adequately warrant the push of dual or quad monobloc amplifiers, the Thesis γ (gamma) stereo power amplifier is the perfect proposition for those needing less real estate, but requiring the same poise and purpose of it's fellow line.

For being a Transcap-technology stereo power amplifier, the Thesis γ has an extremely good overall transient response. The percussion instruments sound vividly and life-like, providing the essential base of music. While all other instruments and vocals are in their place, together they create a concert-like atmosphere, where you can feel the wink of the musicians when they make an upbeat of a new measure.

When you own a Heed amplifier you meet technology that you most probably have never seen in action before. Like the almost forgotten (and then reincarnated) valve technology, the output capacitor transistor amplifiers can normally only be found in the deepest recesses of engineers drawers. The technical difficulties of RC-Coupling means almost 100% of todays manufacturers opt for the easier direct-coupled solutions instead. With great effort and countless development hours there is a way to employ an up to date and sonically better sounding RC-Coupled amplifier. Heed have chosen this way.

Like the belt of a great turntable or the output transformer of a valve amplifier, the output capacitor makes for a great decoupling between the amp and the speaker. But the main advantage is the fact that a capacitor is an energy storage device. By design, this capacitor connects directly onto the speaker, with no in-between elements. Power delivery becomes rapid and precise. To charge this power element, Heed use a push-pull complementary Darlington transistor drive stage.

This power transforming system needs to be perfectly balanced. The heart of Heed's Transcap technology lies in the precise adjustment of all the charge transmitting and current delivery channels. This propels all the common amplifier components; mains transformer, power supply, voltage and power amplifier stages, into something radically different. You may see now, this is no ordinary amp and it cannot be measured by common standards. Heed by using these methods, enable the amplifier sound to become thick, warm, yet clear and life-like, as it properly translates the electronic signal into the acoustic world.

The Thesis γ (gamma) stereo power amplifier has been lovingly crafted internally by the craftsman at Heed as one can see from the features above, but it is immaculate in conception in the flesh too. The casing is finished to the highest standard with the smoothest of black powder coated finishes and discrete wrapped sides. The extruded aluminium fascia fits onto the casing supremely and the front panel is gently black lit with white light, illuminating the name subtlety.

The rear of the unit has high quality speaker and unbalanced connections that are balanced appropriately in a measured fashion. Clearly defined and partitioned in black and white like the salient points of the most measured and well reasoned arguments.  The Thesis γ (gamma) stereo power amplifier is driven by the same power, precision and fidelity of the Thesis RC-coupled design, and despite it's more demure stature - will charm, inspire and enthuse any listener.

Available in a black casing with aluminium fascia.
