Metrum Acoustics Amethyst DAC / Headphone Amplifier (Silver)
The Amethyst is our new entry model using our praised
“forward correction technology”. Due to this technology a real 24 bits
performance is realized and probably the most advanced way to give R2R technology new
dimensions. As a result music will be more exiting as details on very low
levels will be audible. The Amethyst can meet the best systems today in
terms of sound quality as it borrows all the good things from our top models
Pavane and Adagio. Like her predecessor the Amethyst is designed for the same
basic frame but electronics have been redesigned for future tasks. In
addition we have implemented a new and powerful headphone amplifier having its
own volume control.
The Amethyst is using two Transient R2R ladder Dac TWO
modules. These modules can handle extreme high sampling rates but are limited
to current industry standards which have its maximum (384kHz) on the USB input.
The result of this process is an extremely fast and accurate behavior and
brings listening experience on a much higher level. Despite the fact that
both dac modules are build on the same board an extremely high channel
separation of 110 dB is realized. This contributes to flawless positioning of
instruments. The headphone amplifier will drive impedances down to 16 Ohms and gets
his power from a powerful 30VA power supply. When the Amethyst is used as a dac this
power will be available for the dac only.
