They will be suitably packaged along with our standard three month warranty.\u003cbr\u003e\nDenon Said….\u003cbr\u003e\nDenon PMA-850 Integrated Amplifier\u003cbr\u003e\nA new series of Denon amplifiers, incorporating a wide dynamic range, low noise MC amplifier. It reaches the highest class in the most fundamental characteristic of amplifiers both in distortion factor and S\/N separation. By coupling all stages with a pure complementary circuit from MC amplifier to power amplifier using both PNP, NPN transistors, an ultra-low distortion rate of 85 W + 85 W was achieved.\u003cbr\u003e\nA DC power amplifier placing importance on a quick build up characteristic by incorporating a new amplifying element.
