If that's what you think you are doing...
Perhaps I would be more sympathetic to your cause if: A) what I heard in the videos sounded better than the DHT/SET system and/or the original file...but it doesn't to me. If you made an obvious improvement rather than unusual shifts in tonality...I could say, yes you have made it more like what I hear live. B) you didn't think of yourself as an audio god just because you have 40 systems...one really good one would suffice

. Pretty much anyone with DSP can also make their system sound how they want...including dynamic expansion in discrete frequency bands etc. You have done it in analog...a much tougher feat but that doesn't mean it can't be done digitally.
However, when you use songs from the Smiths and from Radiohead I can only compare to the original recording as these are heavily processed studio recordings. It this case, the original sounds better to me, so, yes I stand with the recording engineer over you...
The reason why something like the Perlman piece is important to me. The recording, while perhaps not the top of the top, captures the tone, timbre, shading and dynamics of a real violin very well (AND I know the sound of live violin VERY well), the piano is also pretty good but clearly subservient to the violin in the mix. So, I can compare not only what my playback sounds like compared to the recording, I can gauge what it is doing compared to the real thing (I also have many recordings of live violin I made myself). My ex had a Strad in house (as well as a Guarneri del Gesu, an Amati and a Guadagnini ), so how they all sound different is interesting and educational to hear how a system can capture differences and how close it can get to the essence of the live sound.
