    How is that stuff on the lettering? Many things that do a great job on metals clean the silkscreened lettring right off as well.

    Does that Pioneer use those little propritary speaker plugs or did they wise up by the time yours was made?

    That's the beauty of this stuff Mark, and assumably the reason for the cost. It's natural base stops it from being an all out aggitator. I haven't had any issues with lettering, and the 650 looks mint with no breaks or fading. To be honest, I have never even considered that until now, but that's probably because it hasn't been an issue.

    I can't answer regarding anything about Pioneer. This is my first. I don't know if there is a name for this style, but it's a button which slides the metal over to create an opening.

    I took this photo blind...

    Ya got lucky.

    A lot of older Pioneer amps use these and are a PITA since a lot of stuff you find used doesn't have them. People generally only become aware of these when they get it home (or unpack it) and go to hook up speakers.

    That discovery is usually followed by a fairly vocal "WTF???"

    I call what you have "push-to-insert" terminals and were the most common type then.

    Let's speak kindly of the aged. I've got a Pioneer SX-1000TD that uses these abominations. It works pretty well but it's in line for a cleaning and a few bulbs, as soon as I can dig up some info on it.

    And my SX-1500T uses them too. What you have to remember is that these were the first of the direct-coupled amps to be put into Pioneer receivers. If you cross the output jacks on a direct-coupled amp you can fry the output transistors in a flash. (tried that once with my PS Audio 200c and welded the leads!) With the whacky Pioneer system you can't do that at the connection jack.
