RB300 maintainance...

I noticed that on the most inner grooves especially on the extra long-playing records where the grooves come as close as possible to the record label that the sound greatly degrades and becomes too mushy and undetailed. It happens approximately 1.6" apart from record label. Before that the degradation seems to be unaudiable. The very beginning of the playable surface seems to be even too bright, but that's I believe an issue of a load impedance and can be easily resolved.
I checked the cartridge allignement and it seems to be at its maximum precision.
I assume that tonearm moves heavier towards the inner grooves and needs some attention.
Please help me out. My analogue setup is J.A.Michell GyroSE/Incognito-RB300/Lyra Helikon(Benz M.09 as backing up)

THANKS!

Make the following arm test:

Place the stylus guard in place, and put the arm in perfect balance at zero grams, the anti-skating at zero too. Then slighly tap with your finger the arm to slide it towards the spindle and to the back, to rest position. The arm should be travel free as a feather. If you noted hesitation or any anomalies, unfortunally the bearings were damaged in a degree accordingly to the anomallly.

I hope this is not your case, because there no more could be done to fix it, only the manufacturer.
