While extremes of azimuth adjustment do have an apparent effect on channel balance, the cure is worse than the disease, because the stylus tip will be at a suboptimal angle to the groove resulting in aberrant wear on both the stylus and your LPs and audible distortion as well. I advise against adjusting azimuth to cure channel imbalance.
Balance control?
I’m running an analog exclusive rig and feel like I’ve been dealing with a channel imbalance for awhile now. I’ve tried trouble shooting this every single way I can think of. The cartridge is set up correctly, checked tubes, etc. My question is: am I obsessing over finding the root cause or should I just cave and use the balance control on my integrated? I feel like it would be ideal to find the cause and not use the balance control. Dose using the balance control introduce anything into the signal? Ugh.

Lewm and Slaw are correct. Using the placement of a vocalist in the mix is not reliable. Even though my speakers are are equidistant from the side walls and the wall behind them my room layout is asymmetrical. I have CD racks on one side and records on the other and the location of doors, windows, electric outlets together with media storage dictated placement of everything that goes against a wall. I am convinced that this is what caused the sound to tilt a bit to one side. The test record and the balance control on my preamp helped me to solve the problem. And when I did, it was like… aaaaahh. Your preamp’s balance control will set you free. Woof |
@woofman74 fair enough. Thanks for the input to you and everyone here. Much appreciated! |
Resurrection of an old thread, but I also run a Herron VTPH-2A phono stage. Keith was kind enough to include gain and trim pots for each channel to help with tube imbalance if this is indeed the case. There can be many causes, as per the posts above, but if you trace it back to the phono stage don't be afraid to try a little trim. |
@bimmerman2 wow really?! That’s very cool. Yeah Keith is a very helpful and pleasant guy to chat with. What are trim pots? Are they different from the loading plugs?
