Any Lumin streamer will work well for streaming only. They only have DAC that serves the streamer itself with no auxiliary inputs for a CD transport .
To the OP. I two systems. I have the cxn v2 and the bluesound 2i. I have compared them both in both systems so I may be able to help.
My only complaint on the cxn is it doesn’t play MQA. Of course the bluesound does. If I did it over again I would have bought the upper Cambridge model that does play MQA. However I actually prefer the sound of the cxn playing cd quality over the bluesound playing MQA. The cxn just has a pleasent sound signature.
With that said I recently added a Hegel HD25 dac after the bluesound and it sounds great so you may want to consider looking into that route.
Hope this helps, lots of choices.
