The CD-306 has seperate DAC's for RBCD and SACD. You would need to burn in the circuits seperately.
I have had my CD-306 since new and have not noticed any gains in SQ after 100 hours. It probably keeps on getting better with more time on it, but the gains are so slight and so incremental that (to me at least) it's inaudible.
