The Kenwood stuff is nothing much. The receiver was about $200 new and everybody knows that most of the consumer audio gear really went down hill after the 1970s. It is also about 12 years old and internal components could be starting to really deteriorate, particularly if it was not well cared for. The cassette deck is average and should be checked out, cleaned and demagnitized. The Denon is an average 5-disc CD changer and should still be servicable, but may need cleaning as well. All in all for $70 you didn't do badly. How much do you have to spend for speakers?
