There is now way to remove overtones/harmonics of instruments as long as amplifier/pre/DAC has adequate bandwidth. The only thing good gear can remove is coloration, noise and distortion.
In the audio vernacular there is what’s described as "sins of commission and of omission". Some components are in my experience more adept at capturing or retaining these important musical elements such as tone density/timbre/harmonic overtones.
I readily acknowledge that when listening, people key in or are more attuned to certain sonic characteristics. So not only do individuals hear things differently, but there’s also the added element of different focus and attention. I can only report and describe what I hear. Another listener could very well have a much different perspective/listening experience.
Some audio components just sound overtly lean/thin/clinical/analytical and I do not like this presentation. It sounds synthetic and un-convincing. Someone else may interpret this same presentation as accurate and dead on neutral. Inherently subjective it is.
I understand there will be discrepancies with assessment of audio component performance. I just know what sounds right to me (And maybe wrong to someone else), that’s all. I can understand the comments from the OP of this thread and the absence of an emotional-musical connection. I get his point.
