Khozmo in Poland makes passive preamps with dual mono volume controls using your choice of their very high quality ladder, shunt, or stepped attenuators. Remote controllable too.
Preamp with separate volume control for each channel?
Thought I should ask you knowledgable folks for thoughts and recommendations. Recently had my vintage Music Reference RM-9 repaired after losing the left channel. Now it produces output, but at a considerably reduced level: Left side volume at 9, for instance, while right side has to be about 5 to match output.
I'm using an old Promitheus Transformer Based preamp to make things work; tried a different passive with a single volume control and it just didn't work.
I had some issue with the repair shop regarding the amp and am reluctant to take it back to them.
Thanks for any input.
