Good Entry-Level DAC


So I had a nice California Audio Labs (sort of ) tubed  DAC that I used with my Rotel CD player. It ,made a huge difference to the sound; after getting it, I re-discovered my CDs! 

I moved over to a NAD C516 BEE CD Player (I know, entry level, but that's what I've got) a couple of years ago or three. I found the DAC didn't make any audible difference; so I sold it.

I think the NAD has a pretty good DAC Chip ( 24/192 Cirrus Logic Delta/Sigma DAC, whatever that means). Is there a reasonably priced ( < $1K) DAC that could significantly improve the sound?

Ideas, anyone?

Since you liked your previous tube DAC I would try MHDT or the Black Ice suggested by freediver.
With your budget in your shoes I'd be looking to find a used Ayre Codex.  Should be able to pick one up in the $900 to $1000 range.
I'd also be much less concerned with the DAC chip in play.
Much more concerned about the total implementation of the DAC.

Doubtful. 
Take a look at the Schiit MultiBit DACs with the Unison USB input boards.  To my ears, their MultiBit DACs are the only thing that sound like real music.
