@noromance , Please and really, I do not mean this as a reflection of you but I have seen people tolerate a lot worse! Any cartridge will track at 10 grams. Don't you remember the days when we put a penny on top of the head shell?
@rauliruegas , I was being generous.
My room is also dead centered and I am forever adjusting my balance. Every record is different. Most of the time it is just a sensation of too much energy coming from one side. The singer's voice will still seem dead center. Just a shift of 0.1 to 0.2 dB to one side will take care of it. Yes, I also can usually tell up front how much it will take. I think the problem is that every system is that much different. Maybe one speaker or monitor is just that much more efficient than the other. The best adjusted systems in the world are at best 0.1 to 0.2 dB off center. Anyway, this is what remotes are for:-)
I would like to straighten the record a little. Listening to and enjoying music is a passive luxury. Building a state of the art music system is an active necessity. They are two very different activities. There are chat rooms and one location at this one where you can gush over the music. Here we split hairs over Hi Fi equipment. There are many ways to approach this subject and disagreement is a way of life in any human interaction. If you can't take the heat go fishing.
