Anti-skating problem

I have an unusual problem, it does not matter how much I adjust the anti-skating on my turntable (Oracle delphi V - SME309 and Grado Sonata) I can never get the left channel to sound as detail as the right. I must admit that they are pretty close, (same output levels, same amount of details and depth) but if a play a choral work, (like a Bach's cantatas) I hear the "Shh" from the chorus on the right channel, but very little from the left. Can anyone tell me what's wrong? I checked VTA, Tracking force, Azimuth and the level of the turntable and all are correct.

Any help would be appreciated.

I will never state this in public but I always start with
the 'blanco' LP or the 'blanco part' on the LP. This way
you can see with your own eye what the skating is as well how it works. From there you should reduce the amount involved and observe if there is any 'buzz' coming from the R channel. You can ignore anything comming from the L
channel.That is the only simple part in your (re) search. This way you start from somewhere while by any other method you start from nowhere.

Dear Bifwynee, I deed try to e-mail you my answer but your
member name seems to be incorrect. A 'blanco' LP is without
grooves (plain) and available on some test records. On some
other test records there is only the middle part withouth
grooves.You need to adjust the antiskate till the arm comes
in 'equillibrium' (does not move towards the spindle nor in the opposite direction). From there you need to gradualy
reduce the skate force . Considering the problem in this
regard with your Rega you can rechek the reduction of the
skate force by looking if the tonearm moves towards the spindle on the test record. By replay you should learn how
this work.
