I like the thread, as long as we can stay on topic. As mentioned, the fault I found (in my brief time with the amps) was a lack of fully developed high frequency content. Especially obvious in the decay of cymbals, bells, and chimes. The strike is very, very clear, and the shimmer is present, but the ringing decay seems to be truncated, along with the tone which goes along with it. This missing quality cannot be caused by a lack of distortion, as the sounds I am listening for are present in real cymbal, bell, or chime. I hear them in my system with the Pass, so clearly the source is resolving them, but with the nCore they went missing.
So what I am (not) hearing from the nCore is not due to its tonality (or lack thereof, neutrality, perhaps) it is missing sonic information. I do find the nCore to be quite lean, but that may just be neutrality-in any case slight tonal shifts can be adjusted for in the system.
