Cool, yeah, try going straight Modi -> NBM, nothing else in the chain, no bypasses to other amps, etc. See if that affects anything at all. Just humor me. It might not affect anything! Well, this is more about trying to solve a longstanding mystery where some would hear the NBM/ZDT Jr as having rolled bass (or super poor quality bass) and some wouldn't. Normally this would be fine, except I haven't been able to match this up to user tastes and experiences. Like I've put my ZDT Jr up against the Magni 3 and not heard a bass roll off, so I can't even triangulate ZDT Jr impressions consistently against well known gear. Yeah, I tested two other ZDT Jrs, the loaner units, because impressions were so inconsistent, and they more or less sounded the same. Some slight tube differences, but the channel balance/imbalance on each unit's pot had a slight acoustic effect as well. And you took my jab in stride and responded appropriately. Friends should be able poke fun at each other.
