I want to pick up a vintage SS integrated

I strongly recommend staying away from 70's and 80's era Pioneer and Sansui products unless you find something you're truly enchanted with and money for repairs and refurbishment isn't a problem. Those two companies liked to glue components to their boards with a glue that becomes corrosive and conductive. It eats the legs off components, dissolves traces and pads, and forms new circuits where circuits definitely don't belong. I've heard differing accounts on Pioneer, but all the Sansui stuff is loaded with that crap and absolutely must be removed with chemicals. Kenwood is probably your best bet. Marantz stuff is fairly trouble free too. ALL of it will require a complete cap job though. I don't buy any of that stuff without looking at the schematics and figuring out what needs replaced before I even plug it in. And plugging it in is a horrible way to find out you need filter or blocking caps... because if you do, you'll need a bunch of new transistors too. 

+1 on the kenwood ka-x100 series; yamaha ca-series also had cool vu meters

For 70's era, you can't beat a Marantz receiver, though you might want to recap it via a kit. Also, consider NAD as another option; they make excellent sounding integrateds, especially the BEE series.

Yeah I am definitely interested in the Marantz receivers. But they seem to be desirable, therefore expensive.
