While my AV system is 2 channel, price/performance considerations made me look hard at the world of 5.1 -channel AVRs. I had an equipment failure. Luckily it's summer clearance time. With a little shopping I ended up obtaining locally a floor sample that turned out to be as-new in every way, included all accessories, lacked only a manual and a box, for 50% of street price.
It seems to have the usual collection of decoders for legacy and modern formats and decoders, including 32-192 KHz 16-24 bit, 2-8 channel PCM, DSD, Dolby TrueHD and DTS-HD Master Audio; Dolby Digital Plus and DTS-HD High Resolution Audio.
The 5 power amps are specified ed for 2-8 ohm loads. The two front channel speaker terminals are 5-way binding posts. It has a front panel jack for a portable player. It has HDMI, CV, and old-style video inputs, with several coax and optical audio inputs. It has bass management with adjustable crossover points, and separate graphic equalizers for each speaker.
It was easy enough to set it up as a true 2-channel receiver, and it sounds great.
