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 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.
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.

L-shaped rooms are a bitch to get right. You might have to change the position of your speakers as well.
