I have to admit I am very confused about the problem. In my experience clarinet mouthpieces are the initiating sound generator. As such there is a GLOBAL tendency to the sound/pitch they produce. They can tend bright, dark, resistant, free blowing, reed friendly, not reed friendly, sharp, flat.....etc. But in each case that tendency extends to the gamut of notes on a horn.
You say you have no such issue with other mouthpieces (one is the Fobes Debut of which I am quite familiar). What is it about the Fobes Debut that needs improvement (searching for another mouthpiece)?
So that I get it. You do NOT produce any sort of extraneous sounds from the Debut on your 576? Do you own another clarinet? If you put the Debut on another clarinet and compared the results with the Grabners, do you get the same results?
And just to clear up other potential issues.........do you know how to accomplish a positive pressure test, or a negative pressure test? These will aid in addressing whether a leak has developed somewhere on the 576 that may cause a weird effect.
