Anti-skating problem

It doesn't surprise me, as my post above indicates. Before working on room acoustics I would suggest walking around the right side of the room and putting your ear to all of the pictures on the walls, pottery, nicknaks, chairs, etc, while music is playing that highlights the problem. Often these things are just sympathetic resonances in the contents of the room. It's also interesting that in your original post you identified the left side as having less detail on choral recordings than the right and believed that this was the side with the "problem". As audiophiles we are often mislead into thinking that distortion is detail; just one of the many pitflalls. Oh, and good you don't use those nasty digital sources too often.

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.

Good work, Marty!

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.
