Traditional Class A amps requires always-on capacitors, which is enormously inefficient and generates excessive heat. Class AB was designed to offer a more efficient alternative but sacrificed some sound quality in the process. XD refines the AB approach to ensure any distortion is outside of the audible spectrum.
The result is best-in-class audio quality, clean power and energy efficiency. 851As power comes from an enormous toroidal transformer. Its so big, it accounts for almost a third of the units weight. Its no surprise then that 851A is able to deliver a huge 120 watts of power into 8 Ohms Or 200 watts into 4 Ohms! In simple terms, 851A has the power to handle huge dynamic range with grace.If youre looking to take advantage of a more powerful amplifier, like the 200-watt 851W, in conjunction with 851As leading pre-amplifier, you can do just that with the pre-amp out connection. With its own toroidal transformer, the 851As pre-amp is truly a class-leader on its own. This item is refurbished to a C1 grade standard. All items are fully tested and working.
