Dual Chassis Compact Disc Player

Opus 21 cd player is the culmination of 10 years of digital audio
development. It couples our refined multi-bit dac design with an ATAPI-bus
drive that enables ideal low-jitter design and reads all discs,
including CD-R, SACD-hybrid, and copy-protected discs, with ease. By
moving the power supply and display to a second chassis, the critical
audio circuitry is free of interference, bringing out more detail than
ever. Three-dimensional circuit construction, while more costly,
dramatically reduces signal path for unparalleled precision.

The Opus 21 cd player is the culmination of 10 years of digital audio
development. It couples our refined multi-bit dac design with an ATAPI-bus
drive that enables ideal low-jitter design and reads all discs, including
CD-R/W, SACD-hybrid, and copy-protected discs, with ease. By moving the power
supply and display to a second chassis, the critical audio circuitry is free
of interference, bringing out more detail than ever. Three-dimensional circuit
construction, while more costly, dramatically reduces signal path for
unparalleled precision.
We use the finest multi-bit dacs available, as we have yet to find a
superior alternative dac architecture. Our custom dsp-based digital filter
uses synchronous upsampling, as we have found that asynchronous designs create
audible artifacts. By implementing volume-control in the analog domain, full
performance of the converters is maintained independent of listening level.
• 4 BurrBrown PCM1704 24-bit converters
• 16x digital filter upsamples to 705 kHz/24-bit
• analog-domain volume control
• balanced and single-ended outputs
• digital input operates up to 96 kHz/24-bit
enhancing two-channel home theater

To match the resolving power and musicality of our cd player, we
collaborated with Denis Morecroft of DNM
Design to develop our first power amplifier. These efforts resulted in
the Opus 21 s30, based on the DNM PA3 series of amplifiers. The PA3 is one of
the finest sounding solid-state amplifiers ever produced. The design is
somewhat deceptive: the schematics appear highly conventional, but there are
details which transform the performance. Most important is the the treatment
of the amplifier as a network element and the careful tuning of ultrasonic
frequencies. How the amplifier handles signals beyond the audible range is
more important than believed.
This is not your everyday solid-state amplifier: this approach
requires a sophisticated combination of measurements and listening tests that
result in a highly tuned circuit. Surprisingly, these modifications are not
detectable with conventional audio amplifier measurements, which are typically
limited to audio frequencies. This area of research may explain much of the
sonic differences among amplifiers which have similar measured performance.
We invite you to listen for yourself and decide if this is the best
amplifier you have ever heard!
• 30 watts/channel
• 2 line level inputs, 1 balanced input
• 1 digital input via cd player
• rs-232 input for system controller

The Opus 21 XS is the perfect complement to the Opus 21 cd player for all
of your 2-channel needs. Bridging three centuries of audio replay formats, the
Opus 21 XS adds high-performance playback of vinyl, FM/AM, and digital mediums
in a compact integrated package.
By operating as a system, only the active circuits are enabled, thereby
eliminating noise and interference. The two phono preamps are individually
optimized for MC and MM cartridges, using low-noise transistors and passive
RIAA equalization.
In addition to the direct connection to the s30 amplifier, the XS has both
fixed and variable outputs to work with any amplifier.
Resolution Audio has taken the difficulties out of assembling a high-end
audio system - just enjoy the music.
The XS adds these capabilities to the Opus 21:
• moving coil phono preamp
• moving magnet phono preamp
• FM/AM tuner with RDS
• 5 digital inputs, including USB for PC/Mac
• 2 analog inputs
• fixed and variable analog outputs
• headphone amplifier
• Opus 21 system bus for direct connection to Opus 21 cd player and s30
amplifier
• system remote control
