Resolution Audio s80 amplifier with transformers for Resolution Audio Opus 21 CD player. Perfect condition. Low hours. Original owner. Great combination system capable of driving demanding loads. One of the finest and most musical switching amplifiers ever built. Very musical, open and transparent with excellent bass extension and control. Transformers alone cost $300. Original wooden shipping crate, power supply umbilical cord and manual. Great opportunity for existing Opus 21 owner.
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!
