Creating a New Benchmark
“Saying that an Audio Research preamp sounds ‘big and airy’ is an
understatement. The soundstage seems to spread in all directions at once, the
musicians and singers sounding more life-size and vivid. This is often beyond
what even very good tubed competition achieves, and it has been the defining
characteristic of Audio Research preamps (and the company’s amps, phono
stages and CD players as well).”
At Audio Research, design is never static. No matter how far we push the boundaries of “high definition” sound
reproduction, our team of engineers constantly strives to improve. The REF10 clearly advances the cutting
edge of high definition music reproduction.
Two separate chassis are necessary for ultimate performance. And, after the 20A power inlet, everything is
dual-mono with separate power supplies and audio sections for each channel.
The REF10 is modern and elegant; straightforward and intuitive. The touch-screen allows easy control. Input
names can be relabeled, input gain offset can be adjusted independently for each input as well as tube hours
meter, and display intensity. You can even change the foreground and background colors of the display, with
ten color options for each. Our team has combined resolution, dynamics and tonal accuracy in a way that puts
you within intimate reach of your favorite performers, without compromise.
It’s dicult to describe the sonic attributes of the REF10 because the descriptions are oft repeated to the
point of cliché. The REF10 offers a further level of resolution, refinement and authority that vividly improves the
musical experience in every way. You must hear the REF10 to understand how much more profound listening
to your favorite recordings can be,
