The SR5500 is an embarrassment of riches. Each "current feedback" amplifier produces 90 Watts RMS, sufficient for all but the largest rooms or most inefficient speakers. The 32-Bit microprocessor decodes all Dolby, DTS surround sound formats, and SRS' Circle Surround II. Consider the SR5500's multi-source/multi-room capabilities. Look no further than the front panel inputs to conveniently plug in a digital camera - smart phone, BluRay / DVD player and/or game console.
