I have a pair of balanced Luminous Audio passive volume controls that I can send. You can borrow them as long as you'd like, as I have no use for them in the foreseeable future.
I imagine there'll be some at CJ to listen to. I won't be carting my amp there, but I'm sure there'll be a β22 there to listen from. I'll make it a point to audition such a setup if available.
I actually like the L & R placement, and the screws can easily be replaced with techier ones, though I have no issue with them.
I love the fact that they used mini XLRs for the replaceable cables.
