Searching for CD/DVD Player with volume control


I have an Oppo 970HD DVD player that I run directly into a power amp, using the Oppo's volume control to operate the loudness level. This bare bones 2 channel system is for music and movies alike.

I'm looking to step up to a better DVD/CD player for improved CD playback while keeping the bare bones set up. My budget is up to $400 on the used market.

What are my upgrade choices for a DVD player with variable output?
Marantz, Cambridge, Arcam, Pioneer, Denon, etc?

The only thing that has changed is your budget, and that was only $100. Do you think that by going up $100 more that this will expand your options ?

A few members offered suggestions and maybe what you are wanting in this price range cant be found and expectations are set to high.
That is why I am asking.

Suggestions include modding my Oppo which is to expensive, and adding a DAC which would eliminate the volume control to my power amp. Neither of these help.

I noticed that the Cambridge 540 DVD player had a volume control on the remote, but I don't know if it controls its audio output, or if this older unit is better than the Oppo.

What about other brands...that is my question. Does anyone have experience with another DVD player. I know many cdp have volume controls, so I'm asking about DVD players.
If there were other options that were in your price range, I am sure members would have mentioned this, but as you see, you are limited.

Why not just keep what you currently have ?
