NAD Pre-Pro Dreams of Doing 4K

NAD wisely hedges its bets with a modular design that enables the M17 surround pre-pro to accept a future 4K upgrade. Another modular upgrade, which literally piggybacks on the preceding one, is a BluSound wireless card. Mate it with the M27 amp with 180 watts time seven into eight ohms. Pricing is $5500 for the pre-pro and $4000 for the amp.
