bought one brand new in 1979
small problems but fantastic sound
stereo/mono switch has to be on mono for stereo sound/phono push-in buttons dont make tight contact anymore but a little jiggling solves the problem/trying to correct if anybody knows solutions
let me know//radio and cd sounds just like new

I got one of these from my neighbor and it blew my old junker out of the water I use this receiver to run a pair of Kenwood kl888x speakers for my pc audio had to custom make my desk and nightstand so I could rack it somewhere and so my desk could take the massive bass this thing puts out.

Pioneer Electronics at its finest. Practically flawless in design and execution. It's toroidal power supply and filter caps represents trends that later came to be editorialized as High End when incorporated into dedicated Power Amplifiers. It delivers outstanding power to the loads it was designed to drive. Tone, Dynamics, and Noise far exceed what's too often found in Home Audio today. Unhesitatingly recommended!

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.



re: SX-1080 KC

Would someone please post a .pdf of the Owner's Manual of this magnificent piece of Audio History? TIA...

re: SX-1080 KC

I've scanned and uploaded my copy of the SX-1080 S S/G version of the Owner's Manual. I know that a KC copy was bought on an auction site last month for a very reasonable price. (Thanks auction site saved search...) If you're the person who bought it, please consider scanning and uploading it here. The only true difference is the voltage selector page, but it's better for all of these to be scanned to online sources. Bad things happen to paper all the time. Just (rhetorically speaking) ask a Librarian from the ancient city of Alexandria...we might well HAVE warp drive by now if that hadn't happened!

re: SX-1080 KCU

For anyone who might be interested, I have an original OM for the Pioneer Classic Silver Receiver SX-1280 on its way and it'll be fine for HFE to delete my low-res stop gap version on that page after I get it uploaded. Thanks, HiFiEngine. You've saved my restoration "bacon" MANY times over these years.

re: SX-1080

I purchased a two month old, SX-1080 in 1978 while stationed in Kaiserslautern Germany for the Army.
It has been the best purchase I have made in my life.
Mine exceded all standards in every aspect of true high quality audio performance. The rich and crisp sound was delivered through a pair of Pioneer tower speakers with digital light sound bars on top of each.
Unfortunately I can't remember the model of speakers that came out at about the same time. I bought it with relatively zero knowledge of hi-end
stereo systems... from a fellow army buddy who wanted to upgrade to an SX-1280... for far less than he paid, less than two month prior.
The SX-1080 was my introduction to the world of stereos. I loved it dearly for years after returning to America and recently saw one on eBay for $1200 USD.. almost three times my purchase price.
