Variable analog output cdp under $800 used?

Alright I'm looking for a variable analog output player to connect straight to my amps without using a preamp for now.

I would prefer a tube player, but SS is ok also.

My amps will be Cary slam 100 mono's or Manley snapper mono's, whatever I can find a good deal on first.

I'm working with a $800 budget for the source

Thanks
