I have a Rogue Audio Sphinx integrated amplifier for a basic two channel setup for my VPI Scout. The amplifier has three knobs: one for input, the other for channel balance, and the third for volume. I have my turntable set up accurately, and I have spent much time thoroughly getting it properly aligned and adjusted. Sometimes I feel like I want to slightly (very slightly) adjust the channel balance on the amp. Does anyone adjust this usually? Why do hardware companies make this as a feature? Sounds like a dumb question, but I am just curious as to how many listeners adjust this while listening to vinyl. It could be the acoustics in my small listening room or speaker placement, but some recordings I want to slightly adjust the balance. Thoughts?
