Up for sale is an absolutely mint and unused Resolution Audio Opus 21 CD player set, with an s80 integrated amplifier. If you are looking at this, you probably know how fantastic this system is, and that you can no longer purchase this setup. This is quite possibly the only unused system of its kind available for purchase.

Opus 21 CD Compact Disc Player
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
Opus 21 PS (Power Centre)
The power centre serves not only as an outboard power supply, but also as a central controller for the full Opus system.
It is included with purchase of the cd player and contains all of the logic necessary to control any Opus series component. When the system is powered-up, the individual components identify themselves to the power centre, which then knows what capabilities are present.
When the s30 amplifier is added to the system, a 100VA toroidal transformer is added to the power centre to supply the amp’s main output stages. The power centre has provision for a second 100VA transformer for future amplifier products.
This flexible design affords all of the benefits of external power supplies, while minimizing the number of separate chassis required.
Only a single power cord is required for the entire Opus 21 system.
S-80 integrated amplifier
More power. Less complexity.
Built using the same design principles as the s30, the s80 integrated amplifier substitutes a highly efficient UcD modulator for the output stage. Conservatively rated at 80 Watts per channel, this amplifier will happily drive any speaker.
The UcD modulator overcomes all the shortcomings of previous class-D designs, thanks to a patented circuit that uses feedback after the output filter, directly at the speaker terminals. This removes the filter from the closed-loop response and eliminates speaker dependence that is all too common in class-D amplifiers. The s80 will drive complex loads without changing character, and is just warm to the touch at any power level.
The s80 is a dual-mono design and includes two large toroidal transformers that are installed in the outboard power centre.
The complete system uses a single power cord and does not require interconnects. Just connect the speakers, forget about the equipment, and enjoy the music!
• 80 watts/channel
• Dual-mono construction
• 2 line level inputs, 1 balanced input
• 1 digital input via cd player
• RS-232 input for system controller
• Integrated remote control
• CD player and amp share power supply
Included are the original packaging bags, cables, remote and instructions.
