I'm curious about a 808v5 CD player with ID41 card ...

Can this be used just as a CD player, would it have to be configured to work with an 861v8, also DSP Speakers?
What would I need to do to use the ID41 card for? Also do I need Roon and would I have to add quite a few extras.

Also seeing Meridian deleting the CD player, would it be a wise purchase, in relation to repairing these units should you need it in the future?

My other question is would I be better off buying the 210 streamer and implementing this component into my present system?

Excuse my lack of knowledge in this area, I really struggle with some of this streaming and especially the Roon thing.
Also Trying to get over a bad bout of depression and I'll health.

Any help on this area would be very gratefully appreciated.
Yours Sincerely Ronald Griffiths
