Nakamichi PA-7A II, Nelson Pass Designed Power!
Nakamichi has long been known for exceptional sound quality and innovation in their product design and development. From the simplest cassette decks to the most advanced all-in-one system, Nakamichi has historically delivered on that promise. Their power amplifiers were no exception. For several years, the world-renown designer, Nelson Pass, achieved some of the highest levels of amp performance under the Nakamichi brand. The PA-7, despite some early design faults, was instantly loved by reviewers for its punch, neutrality, and sweetness. The later PA-7A II improved on this performance and also solved some of the overheating issues that plagued the original design.
The PA-7A II's massive toroidal power transformer and power supply caps set the foundation for what ends up being an absolute masterpiece in amp design. The stats on this amp are superb, delivering 225 watts per channel into 8 ohms, and 330 watts per channel into 4 ohms with negligible distortion and a 120 dB signal-to-noise ratio. The high damping factor and Class-A operation give depth and breadth to music even at low volumes. In addition, the amp runs Class-A up to 45 watts per channel, nearly double the Class-A output of its contemporary competitors. What Nelson Pass achieved was truly remarkable, even by today's standards.
This amp is in good physical condition with only a few minor bumps along the tops of the rack handles as shown in the photos. It sounds utterly perfect in every way: smooth, powerful, uncolored, and effortless.
