Priced at $3,499, this 160-watts-per-channel seven-channel amplifier has some serious spank. It's built like a tank and comes with a design that included seven discrete channels of amplification capable of dipping down to a whopping 400-plus watts per channel when given a two-Ohm load. The NAD Masters Series M25 has been THX Ultra2-certified, meaning that their power ratings meet THX's high standards and avoid the spec gamesmanship seen with other products. The sound of the NAD Masters Series has a hefty low end but also, more noticeably, a smoother mid- and high-frequency response than the lower-level NAD line. In a recent private demo with an NAD Masters Series system, paired with PSB's newest reference bookshelf speakers, I was treated to a very wide soundstage and out-of-the-box imaging that is normally reserved for systems costing much, much more.
