Integra Research RDA-7.1 Amplifier: First Look

  • Price: $5,000
  • Channels/Power: Seven channels; 150-Watts per channel into 8 ohms/300-Watts into 4 ohms
  • Inputs: Single-ended and balanced

The RDA-7.1 represents a unique collaboration between Integra Research and high-end audio's Balanced Audio Technology and the latter's co-founder and chief designer Victor Khomenko. Although BAT is best know for its outstanding two-channel tube gear, the fruit born of this unusual relationship is a THX Ultrra2 certified seven channel solid-state amp with low feedback, a fully balanced topology and healthy 150-Watt per channel power rating. The bandwidth specified as 200kHz, which is perhaps more important than ever in home theater and both Blu-ray and HD DVD have the potential to carry hi-resolution digital audio signals. In stores now.
