There is one of the last Kenwood quad receivers on ebay. I had the one up from this for a few years, and always liked it. It claimed full logic, although the decoding never really impressed me. I got my Space and Image Composer when I was still using this receiver, which didn't help my impression of the decoder. Also, has no cd4, untilke Sansuis. On the other hand, it has lots of power, sounds good, and many, many imputs/outputs. This guy claims he never used it after buying off ebay, which means you should save money for likely repairing it. Anyway, if anyone is interested, here's the link. I have no connection with this seller or this particular unit, just my $.02 on the design.
