A:AnswerYes, you can change all the CDs except for the one playing. It will allow access to the tray for all slots, but will hide the one that is actually playing, so it is very easy.
A:AnswerYou have to use the optical plug if you’re going to play the cd player through the Yamaha receiver, I had to run to Walmart to buy the optic plug!
A:AnswerYes, since it has line level outputs.
You have two options:
1. Player => Power Amp => Passive Speakers
2. Player => Mixer => Power amp = Passive Speakers
or use Active Speakers (which have build-in power amp) instead of Power Amp and passive speakers
PS There are power mixers which also have built-in amplifier.
A:AnswerIf the Kenwood has typical line level RCA inputs you are good to go. But I think you are wondering if a modern CD player is compatible with a older receiver. I use the Onkyo with a 1990 Yamaha receiver and there are no issues with incompatibility.
