@David B Re: Bass Boost. I am very perceptible for tonal changes, and in general, my hearing is very accurate…
I do think it is actually due to my Autism. I think I have a great strength there.
Of course, I would feel, if it is 'off'. I would immediately feel it.
David B I just tested a MIDI file of mine across the D274, CFX, 1904 Upright.
Results: Inconsistent intonation. All sound 'lazy'. Like, it doesnt matter if you hit note X like X. Like, you would say Ah-dunno instead of "I do not know". Sounds like phrases are just consistently not on point. Even with forced 50% dynamics.
I like none of those Pianos. When I visited the Piano House years back, I actually Preferred a Schimmel C…. something for its distinct and clear tone.
