NAD was at the show with a slew of new products, among them a revamped 4-model AV receiver line: the T 748 (100 watts x 7, $900), T 757 (120w x 7, $1,600), T 777 (140w x 7, $3,000), and the flagship T 787 (shown here, 200w x 7, $4,000). The big news for enthusiasts is that NAD's future-proof MDC design has moved down in the line and now begins with T 757, the lowest price yet for an MDC receiver. MDC stands for Modular Design Construction and allows the unit's input/output circuitry to be user-updated as needed over time to swap in new HDMI versions or introduce new flexibility. Portions of the receiver's jack-pack are on slide-in/screw down modules that can be changed from the rear panel. Home Theater's review of the T 757 is coming soon.
