This is one massive amp. Measuring 20″ wide, 17″ deep, 10″ tall and 84lbs, the RB-1590 is the very picture of what a 350W amp should be. With dual toroidal transformers, the RB-1590 is actually two dual mono amps packed into one. There was an air of effortless control over all kinds of music that was pass through it. Bass slam was quick and “deadly”. Its like having a huge hammer slamming down on the low notes when the need arises. Mids were strong and rich with highs displaying a smoother extension. The $3,000 MSRP is an unbelievable bargain considering the quality built, high end parts used and the top notch sound. This is clearly one of the best buys now for high powered amps that cost under $2,000.
Cosmetically, it is in great shape. Minor scuff marks but nothing major. Original box is included.
