He's got a fever - and the only prescription is more Nobsound. Curious to see what @atomicbob digs up on their box as well, though I've happy with the Mackie Big Knob Passive. Channel imbalance is only present for the first few degrees of rotation, then disappears altogether by the 7:30-8 o'clock position. 2x2 balanced I/O. Its knob is big. It sounds like whatever I plug into it. Only potential downside is its use of 1/4in TRS jacks as opposed to XLR, which is a less common connection method in hifi world. Or the feeling of inadequacy that comes with not owning a preamp with wood trim or that spells messages with its heatsinks.
