For sale is a mint condition Resolution Audio Opus 21 S 80 Integrated Amplifier ($2500 new). This 1.5 year old integrated is in as new condition and includes manual, remote and original shipping crate . I will included a $50 Furutech ceramic fuse for improved sound quality. (*Note: I will sell this amp and my Opus 21 CD player for $1849 plus shipping and paypal fees.)
IMPORTANT THIS INTERGRATED REQUIRES A RESOLUTION OPUS 21 CD PLAYER FOR A POWER SOURCE. IF YOU DO NOT HAVE OR PLAN TO BUY AN OPUS 21 CD PLAYER, YOU CANNOT USE THIS INTEGRATED.
I’ve owned the following amps; a Gamut D200 mk3, a Naim NAC 202 with Hi Cap2, NAP 200 and an Ayre AX-7e. The Resolution Audio system is one of the most musical! And it resolves as much of detail as the others. It has the PRAT of the Naim system if not quite as powerful as the Gamut D200’s 200 wpc. The Resolution Audio Opus 21 S80 will have you digging through your CDs in an effort to relearn your entire music collection. Warning: do not listen to it unless you have some time on your hands!!! It offers 1 set of XLR inputs, 2 sets of RCA inputs and a direct input for the Opus 21 CD player.
While many other brands such as Naim and Ayre have increased their prices over the years, Resolution Audio has not! This Integrated is a bargain at $2500 combined direct from Resolution Audio! It is a total STEAL at my price!!!
The Opus 21 S80: More power. Less complexity.
The S80 is a hybrid of sorts. It is designed around the DNM amplifier (the DNM is Stereophole class A rated) principles but uses the award winning UcD switching output stage to deliver 80 wpc to drive a wider variety of speakers.
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!
