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.

Hi Nandric: My TT is fitted with a Rega RB 301 arm. IMHO, the anti-skating control, to say the least, is surprisingly primitive and cheap for an arm having such a nice reputation. Setting anti-skating is at best hit or miss. Please elaborate on the "blanco LP." What is it?? How does it work? Is there any other way to check and adjust anti-skating with some degree of precision? Thanks

Ed: For sure -- fair comment. In any case, Nandric's advice is worthy of its own thread. Hopefully, he'll answer my question. Have a great day.

Please check the archives on this topic. I think you'll find much better methods for setting AS. If you can see the effects of AS on your stylus as it settles you probably have way too much AS. IMO, and all that.

You have a good day as well. ;-)

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.
