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.

Folks:

Thank you for your help. Based of you feedback, I started to check all settings on my turntable. After checking and adjusting all settings, the problem remained. After many hours of frustration, I gave up and listened to my SACD player which I have not heard in a long time. To my surprise, it happened while listening to the SACD!! It was unreal. So I checked all equipment (using a headset with its mini-amp) from turntable, CD, SACD and preamp, and guess what, the problem was not in each device. Only the amp and speaker was left. I checked these by switching channels (left and right) to see if either the speaker of the Amp had a problem. I even pulled out a pair of old speaker to test the Amp. After all this, I had an epiphany, it’s the room. Something with the room make the “Shhh” sound more from the right side than the left. I have an L shape room with the right speaker having wall 4 feet from one side and the back. The left speaker have the back wall 4 feet away, but no wall to the right of it.

Any suggestion how I can tune this room?

Thanks

I appreciate your feedback. Tonight I will do as you suggest and check for any sympathetic feedback. I guess I fell into the pitfall. Further testing using a test CD, I also discovered that the left side produce bass distortion, it sounds lagging, like as it’s inside a box. Today, I purchased a copy of “The Complete guide to High-end Audio” by Robert Harley to read about room acoustics. He wrote about “L” shaped rooms and suggests placing a bass trap at the left corner to resolve the bass issue. However, it does not address the detail issue I outlined above.

Once again, I am humbled by Audio. Just when I thought I had it down, it proved me wrong again. But you know what, I love it thought.

BTW, I really dislike Digital on music. Even thought, I had spend a fair amount of $$ purchasing the latest on digital SACD Player, DVD Audio, decoder, etc. still it does not come close to the satisfaction, depth and level of details analog have, but I am sure you know this.

It is likely to be the cartridge. When building a cartridge and the top ones are mostly hand built, extremely fine parameters are in play along with very thin coil wire and a stylus which is difficult to see with the naked eye. There is lots of room for misalignment in manufacture.
