CD Player Advice

Figured this would be the right place to ask for some advice on finally adding a CD player to my setup. I'm going the FB marketplace route and there are three Marantz ones currently on there. A DV6600 (DVD & CD Player) for $100, a CD 6004 for $400 and a SA8003 for $500. These are pre-haggle prices. I'm not really in the mood to go down a research rabbit hole so I ask you community, what would you buy. I'm pairing this with a McIntosh MA252, some KEF LS50 Metas, and a SVS SB-2000. Any other suggestions also welcome. Thanks!!!
