Sparkler CD Player or Transport?

Hi all-

I’m trying to put together a system that needs to tuck into a shallow cabinet.  The new Sparkler 515 player or transport seems perfect.  Has anyone heard this yet (and compared it to the 503 which it replaces?). I’m also wondering if I am better off  with the player or with running the transport into an R2R DAC (Border Patrol appeals to me because of its size).  I’m sort of leaning toward the player because of the simplicity of a single box.. Amplification is Wyred4Sound and speakers are Harbeth P3ESR.

I only play redbook cd.

Thanks for any thoughts.
