The new Peachtree GaN400 Power Amplifier employs GaNFETs (Gallium Nitride Field-Effect Transistors) for generating its 400 Watts of output power. Why GaNFETs you ask?
From Peachtree:
The GaN400 achieves new levels of performance and efficiency by utilizing GaNFETs instead of MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) that have been the industry standard for more than 50 years.
…
GaNFETs turned-on ~4 times faster and turned-off ~2 times faster reducing switching distortion (ringing) by several orders of magnitude. This, in-turn, allowed designers to use much less global negative feedback to achieve excellent measured results. The result is an amplifier with exceptional musicality and excellent measured performance. In other words, an amplifier that provides wonderfully natural sounding music reproduction like the best tube amplifiers, yet retains the tight bass, extended frequency response and sheer dynamics of the best solid- state amplifiers. It really is the best of both worlds and all of this is accomplished in an amplifier that is also one of the most efficient designs in the market today converting ~96% of the electricity from the wall into usable power.
If you’re not familiar with Peachtree Audio, they are one of those audio companies that specializes in bang for your buck, with near zero malarchy. So when Peachtree says something like, an amplifier that provides wonderfully natural sounding music reproduction like the best tube amplifiers, yet retains the tight bass, extended frequency response and sheer dynamics of the best solid- state amplifiers, I immediately think — I want to hear that!
The GaN400 houses an 850-watt RMS regulated power supply, offers balanced and unbalanced inputs, an aluminum front panel, and in typical Peachtree fashion, a chassis wrapped in real wood finished in Gloss Ebony Mocha, Piano Black, or a Limited Edition Ash finish.
Peachtree is also offering a bundled price for their preDAC + GaN400 that comes in at $4498, or a cool $1000 discount from the price as separates. Nice.
