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?

I’ve had good luck with my Project Pre Box S2 although I am trying out the NAD C658 for the added benefit of BluOS streamer/ Dirac room correction and Phono input. 

Good luck.

RME ADI-2 fs DAC. Music I thought I knew well, I’m hearing information I have never heard before. New can be had for $1099. The RME is hands down better than my Cambridge 851C which is a respectable deck, so it should be just as noticeable on your NAD if the rest of your system is up to it. The DAC input on my Cambridge is much better than using my Bluesound Vault 2 direct. When I purchased the RME, I was hoping it would surpass my Cambridge but I wasn’t expecting it to pounce on it... it’s not even close.
