Syntax, I suppose I should explain in more detail. I set VTA visually and by listening and was happy, then acquired the ability to measure, and found I was off the recommended VTA by 2 degrees, when I attempted to set it at the recommended value, it sounded worse, "cognitive dissonance and that", just wanted to see what experiences others have had with this. Perhaps it is not to use a measuring tool and just set by ear. I would however be interested in what the measurement is when it sounds right on others rigs.
