A CD PLAYER whose sound quality NOT AFFECTED by the DAC?

Get a CD transport and be done...then you can buy a dac to suit your taste. 

As just said by @mahler123, there were very few Multi Disk Players that sounded any better than a portable player. CAL and Rotel had decent ones but any mass market unit is compromised for convenience.

I am very happy with my Rotel 1572 CDP (Balanced into my Lux) that replaced a 1072 which both easily bettered my 2 OPPO 93s

What @audioguy85 said. 

When I purchased my BlueSound Node 2i, I also purchased a Project DAC.  I tried to convince myself adding the Project DAC sounded better.  However, I noticed the bass sounded thin as compared to just using the BlueSound so I ended up selling the Project on Audiogon.  

Can you really hear a significant difference between a BlueSound and a more expensive streamer?  If so, what would I hear that is significantly better?  If so, what streamer would you recommend?

I have 3 Marantz cd decks...there built in dac is fine.
