Krell Class A iBias Technology
Krell’s history is rich with breakthrough Class A amplifiers that have helped build the Krell legacy of offering the best sounding amplifiers available. Audiophiles have always considered Class A technology to be the best sounding operating state for amplifiers. However, despite Class A’s unrivalled sound quality, it has fallen out of fashion because of recent demands to reduce power consumption and heat in home electronics products. Krell engineering took this challenge and redefined the meaning of high performance power amplifier. Our goal – unmatched performance, elegant design, and a compelling array of features. The breakthrough – a patent pending circuit delivering Class A operation without the excessive heat and wasted energy of conventional designs, housed in a striking new form factor, with network connectivity for advanced access and monitoring. The sound is open and unconstrained, in a manner that rivals live performance and the true sound of voices and instruments. Music and dialogue are reproduced with a richness, detail, and startling dynamics that fill a room.

When developing the TRI300-XD, David Goodman, our Director of Product Development, whom has been with Krell since 1987 and was largely responsible for design work on all Krell products, discovered that with modifications to the output stage, we could vastly improve sound quality, across the board, to all of our amplifiers.

A deeper, darker, blacker background that provided significantly better macro and micro dynamics, more silence between the notes. Vocals and midrange took on an organic, yet more vibrant tone, enabling us to hear much more body, and even though our amps were great before, there was a very significant improvement.

The speakers disappeared; yet, instruments were more focused with appropriate size and specific soundstage locations. All in all, a much better sounding, much improved experience that was easily, immediately heard by all that listened.
