I have a Sony STRDH130 2 channel stereo receiver. It is in immaculate condition and very well taken care of. This was an extremely popular model when it was released and I can attest to all of the 5 star reviews. Sounds amazing with some good speakers. All functions are tested and working, and can be shown working upon request. Would love to keep it, but we upgraded to a TrueHD 5.1 surround sound system.
