Thank you. I completely understand the “right” approach to address this need but I would like to keep my current preamp/amp. I know some folks use an in-line tone control device, e.g., Schiit Loki, etc., to tweak the sound and was wondering if there’s a similar gadget out there to just control the balance. I suppose it’s not that difficult or expensive to build a dual volume control box using premium grade attenuators such as Alps, etc., and that might be an option to pursue if there’s nothing out there for this specific purpose.
