I have absolutely no experience with the R1 so cannot comment on its sonic signature but if your R1's were cryoed and not burnt in following the cryo (I believe Alan Kafton at Audioexcellence burns all his in but am not sure about other vendors) then the sound you are describing would be typical of cryoed, non-burned in receptacle.
Ask your seller if 1) the receptacles were cryoed and 2) if so, if they were conditioned post cryo. If the answer is yes to number 1 and no to #2, take them out of your system and put them on a fridge or chest freezer for about a month, burning in each half of the receptacle for about 2 weeks.
Then put them back in your system.
