DETAILS

          
Simply put, the REF150 SE is a breakthrough in stereo power amplification.  Replacing the REF150—which was one of the most respected modern stereo amplifiers—was a daunting task, but it has been accomplished.  The REF150 SE offers more power, greater dynamic thrust, a more vivid and resolved presentation, greater finesse, and quieter operation.  It is the new benchmark. Having identical outer dimensions as its predecessor, the REF150 SE has much more packed into its chassis.  Refined front-panel cosmetics reflect the updated look of current-generation models, with silver units having silver handles and silver top covers, while black units have black handles and black cover.  (Colors may be mixed to match older models.)
