Marantz = No. They were owned by Phillips prior to D&M Holdings and they did, and as far as I know still do, provide the basis for their players.
If you can find a decent Sony ES player, I have no problem recommending them. Their normal players were pretty average, but the ES players are decent.
Used Rotel, NAD, etc... would also be good. The current NAD stuff isn't as good IMO, but the older stuff is relatively bulletproof.
