The T975 employs mono-block construction for each of its seven channels. Every element of each channel's circuitry, save the power supply, is fully independent thus eliminating inter-channel influences as a concern. The T975 employs active ground isolation to further eliminate any possibility of inter-channel interference even when more than one preamplifier is driving the power amp (as might be the case in a custom installation). Each section features an FET Class A input and driver stage circuits, and a high-current output-stage design, employing high speed, discrete output devices to promulgate superb dynamic quality. The result is musical detail, impact, and soundstage stability and depth unmatched by multi-channel amps of even two and three times the T975's price. The 7-Channel NAD T975 is a perfect accompaniment to the T175 A/V Tuner Preamplifier.
