Apollo R + Codex v. different CDP or Ayre QX


My current system is an Ayre AX-7e with Apollo R or MH 5 TT as source, with Sig 2 Ce’s.
 I mostly listen to CDs and look forward to more streaming via Tidal or Spotify Hi Rez(use both).
Ultimately I plan on following the Ayre/Vandy upgrade paths. 
Ive been thinking of adding a Codex and using the Apollo as transport to the Codex via Toslink, vs adding a different balanced CDP, vs waiting for Ayre to release more in the 8 series. 
As to other CDP’s I was thinking of a used ARC CD8($4,500- IDK on tube hrs), or Cary 306 SACD($2,750), both of which have BurrBrown DACs and balanced output l. 
A recent conversation with a dealer that’s expert in Ayre and Vandy, suggested I wait for the 8 series release, and hinted at an Ayre spinner release in the not distant future. 
Thoughts?
Thanks

Thats a hard question to answer because I don't really know what your listening priorities are. For me, the upgrade will be worth it in my system. The difference between my current setup, which sounds good already, and the system using the EX-8 is significant enough to do the upgrade. My Harbeth's responded really well to to the increased bass, air, timing and resolution that the EX-8 offers.

I would suggest you hear it yourself to decide if it's worth it but I think you said it in your post, "I do not see the need to upgrade". I suggest if you are really happy with your sound now, stick with it and enjoy! 
@tomic601 Can you suggest a glass Toslink cable? I see them online from cheap to rediculous prices. The one I found so far that looks good and is still reasonably priced is Lifatec
