A question for the audiophiles. For the first time in many years I played a vinyl record (remember those?) only to find it sounds distorted, similar to over amplification of a weak signal. Tried another record, same problem. Then a played the cassette (remember those?) recordings I long ago made of those records, and they sound better than the records. All the recordings and equipment are the same circa 1980 ones, except the receiver is a relatively new Onkyo. Since the receiver is the only changed component I am suspicious of it, OTOH it plays other input sources just fine. What about the photo cartridge? After decades of non-use do cartridges "go bad"?
