I am looking at getting a new marantz multi disc cd changer like the current model cc-4300 or even a second hand one If I find one. I was going to buy an older one of ebay (cc-65) but it did not support playing DTS 5.1 audio cds through the optical out as it somehow corrupted the audio (confirmed by Marantz). I currently have 2 marantz single cd players (cd-63 and older cd-65) and they both support playback of dts 5.1 audio cd's no problem. I am planning on mainly playing DTS 5.1 audio cds with it, so must have digital out and will be connecting it to a Marantz sr7500 amplifier. My query is do the latest or recent Marantz Cd Changer models support playback of dts 5.1 audio cd's? and are there any changer models to avoid thet don't play dts 5.1 audio cd's properly?
