Wendell is correct - you should contact me directly to discuss this. For one thing, it seems likely that you are connected to the active outputs - not the passive. Be sure you are connected to the passive outputs if that is how you would like to run the system. In addition, the gain of the active portion of the MLD is adjustable, so you could set it at unity or +6dB, and this might solve the problem. What you are hearing is the less-than-perfect tracking of the volume control down at the very start of rotation (a common issue with stereo potentiometers). If you reduce the MLD's active gain or switch to passive operation, the problem should go away (unless the Modwright-Sony has unusually high output voltage).
