So what you're describing is a change from earlier "refurbs" that didn't have much more done to them other than re-boxing.
VOS- in my post, I said that my first HR20 was new and all the others including the last one (-700CR) were refurbs. The new one was -700. Next came a -700R, then a -700C. All these were off the box they came in. On the current set, the label is -700, without an "S", and, a little added sticker that it is a refurb.
D* seems to have setup some sort of "repairing facility" that the earlier ones didn't go through.
Now I wonder if "R" are those made in Mexico & "CR" are those that were made in China?
The "S" was on the carton but not the unit as all of the -700s are silver, & I'd guess the "C" was for China also.
