Joseph uses a very high quality pot on both the motorized and the manual. The manual is superior to the motorized in terms of channel balance being virtually dead on. We do not feel the preamp is out of balance either at the outputs or at the pot, and I explained why using the specs. It is possible it appears that way to the customer, but that could be because his old preamp was out of balance, because his room is unbalanced, etc.
In trying to reassure people that there is no problem with the preamp, I see I have misled people there is.
In trying to be reassuring, I see I have only succeeded in raising anxieties.
There is no problem with the preamp's balance. We consider this customer's problem, if there is a problem and not simply a difference from his old balance, an anomaly.
