Separates vs. Receiver

Separate components have always been used in professional applications, and occupy the highest tier of performance for consumer electronics products. Simply put, the receiver concept makes compromises in performance and flexibility in favor of convenience and price. This is especially true for the power amplifier section of the receiver. The large power supply and output stage heat sinks of the power amp must be compromised to fit in the single chassis format of the receiver. These high power parts can also cause interference with the lowvoltage sensitive circuits used in preamplifier, tuner and decoder sections of the receiver. The T175 combines all the control and decoding functions in one compact chassis, giving up nothing to the convenience of the receiver, yet by separating the power amp stages gives a big jump in performance and flexibility. The 5-Channel NAD T955 and the 7-Channel T975 power amplifiers are perfect accompaniments to the T175. (Get High Definition in your T175 with NAD's MDC upgrade modules)
