I bought one of these a while back. Needed some work done to keep it in good shape. They rebuilt Power Supply and Regulators. When I had it one channel would fade in and out as it warmed up. I love these meters. The 50 series are great also. still not sure which sounds better SX 1050 or SX 1080. the SX 1080 specs are better but does not always paint the true picture. I also have an SX 1050 which smoked a large power resistor when I turned on they a few seconds later a loud bang occurred. No smoke though so think the main Caps blew. Most of the numbskull sellers on ebay do not know how to package a receiver and they are damaged in transit (Ebay sellers do NOT just set it in the box and hope for the best). 2 out of three of mine were damaged. I had to bend the bottom casings ect to straighten out frames. I have an SX 1250 that is fabulous but miss the meters and is also in for repair. An ebay do it yourselfer futzed up the tuner. Many wires hooked up incorrectly ect. Anyway the SX 1080 is fantastic. All the cheap tv/surround sound receivers of today are junk. These silver beauties are a real treasure. Not sure If I like the earlier Pioneers with the Dark hard to see tuner section but who knows. Anyway If you can get one of these for $500.00 or less go for it. But they may need some TLC to get them up to par since they are over 30 years old. None of the junk is built even close to what Pioneer built in the 70's and 80's. Oh and last but definitely not the least. I love the wood panels. Reminds me of the old station wagons of the past with the decorative wood side panels. Some of the older Pioneers stuff used real cheap veneers that loosen over time but these receivers used real wood perhaps plywood? I love these ancient beasts

this is what a stereo reciver should be. pleasing to look at with a wooden cabinet brushed aluminum large meters and substantial controls that you can feel as they move through the detents. i love the solid feel of the whole thing. i have better sounding amplifiers but none that make me feel the way this one does when turn this one on. im sure if i was to try perhaps a carver or a luxman that they may cause the same feeling but then again perhaps not.
in summary this is just a solid wonderfully built and beautiful component with tons of power and looks to spare buy this and you wont be disapointed.
