No, the blinking CDs are all standard redbook. I have yet to identify a pattern in the incidence of the problem that might shed some light on its origin. But, I'm not grinding my teeth over it. As you point out, there are only a few of us who still spin CDs, which likely accounts for the absence of comments in numerous audio forums about the blinking display. I have a streaming set up (Bluesound Node 2i, Tidal subscription) which sounds really good through the Harmony. I use streaming to find music that I like well enough to buy as CD or LP. I suppose I am just stubbornly addicted to physical media.
