Any suggestions as to a high quality cd/dvd megachanger? I can't use the Sony 400 cd megachanger, as it is too deep(21+ inches) for my setup. I could get by with a 50 to 200 cd/dvd unit. Also, are megachangers a good idea, and are they reliable? Finally, if I give up on the megachanger, is there a high quality 5 disc cd/dvd player someone can recommend? Or is it better to have a separate dvd player and a separate cd player? I will be using a Denon AVR receiver, and I want to maintain high quality audio and video. Will appreciate any and all thoughts or recommendations.
