I am selling my almost new (purchased April 26, 2013) Onkyo TX-NR809. I just don't like the sound of this compared to my older Pioneer SC25. I have all original packaging and accessories. The unit is as like new as it gets. It has only seen about 20 hours worth of use.
You don't like the sound with Audyssey or without? We did some comparisons with amps and receivers in KC not to long ago and nobody could tell the differences between amps, or AVRs if no EQ was engaged. This included and Onkyo TX-NR1007 and a modern gen Pioneer Elite AVR.
