“Three-terminal thermal analogies to electrical transistors have been proposed for use in thermal amplification, thermal switching, or thermal logic, but have not yet been demonstrated experimentally.

LONDON — Oki Electric Industry Co., Ltd. has developed a GaN-HEMT power transistor on silicon substrates that it says dramatically improves amplifying performance compared with other available power ...

Peachtree Audio’s GaN400 stereo power amp ($3,000) blazes new trails for Class D amplification. The amp uses cutting-edge GaNFET transistors in its output stage, delivering a massive 400wpc! Read on.

As we’ve traced our no-nonsense path through the world of Hi-Fi audio, we’ve started with the listener, understood the limitations of the human ear, and thence proceeded to the loudspeaker. We’ve ...

It may not be to everyone's taste, but this brand new monobloc amplifier from McIntosh cleverly blends both vacuum tube and solid-state technology in one chassis. If you’re not a serious audiophile ...
