I don't have an answer to that. At a circuit level Noble actually has more in common with a B15 preamp than with More. Noble and B15 both use a pair of inverting gainstages so your output is in phase with your input, whereas More uses parallel inverting gainstages and parallel non-inverting output buffer, so your output is out of phase with your input. So I don't think it's a phase thing. I think it has more to do with frequency response and interstage impedance coupling, but it could also be more of a "feel" thing than a "sound" thing, which makes it hard to explain.I've noted this "3D" effect with a couple different setups, and the MORE definitely has this a little bit. What are the electronics/physics behind this? Does it have to do with how the circuit treats the phase, etc? Why does a Noble/Nobelium/MORE do this, but not a B15 (that I've heard)?
