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!

Patrick, Rega is an excellent value but the Rega's philosophy is to place too much demand on the turntable isn't sometimes appropriate. I believe that adjustments to turntable/arm for the sake of maximum cartridge accuracy must be mutual. If I were using fully adjustable arm that would not be a problem at all. Now I'm mobilizing my file to scratch the right plastic sylinder and than measure the level every time I scratch or maybe I'll be cutting plastic spacers from soft guitar pick so I will not do any damage to an original settings.

Marakanetz,

I agree with your philosophy regarding a synergy between the table and arm. Good luck and oh yes, the guitar picks sound like a good way to go.

Later,
Patrick

Good for us to hear differences! -- The problem had been resolved with recyclable party plates and guitar picks where necessary. Still hear the differences but much-much lower and on acceptable level.

RB300 after all isn't easy arm to set up properly!
