  • The new DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) dampens super high frequency distortion while Closed ground-loop circuits, HICC (High Instantaneous-Current Capability), and vibration-damping construction produce a stunning sound through a wide dynamic range.
  • Power in spades is ready at your disposal thanks to four 15,000 ?F capacitors.
  • The efficient parallel push-pull design when paired with the three-stage inverted Darlington circuitry will have distortion almost eliminated.
  • The Classic design doesn’t exclude modern formats the A-9070 is equipped to handle 192 kHz/24-bit HD audio playback.
  • Separate Wolfson? 192 kHz/24-bit DACs for both left and right channels improve performance and flexible integration options from four discrete amplifier modes for use with other Hi-Fi components?integrated amp, power amp, pre-amp, and split pre-amp/power amp.
  • Attention to detail is on display with an independent headphone amplifier, a phonograph equalizer, three digital audio inputs, four analogue inputs, and gold-plated audio terminals/speaker posts so the amp’s pedigree is sure to impress. Audiophiles needing a top-shelf stereo amplifier, your search is over.
