Atmasphere,
I have huge respect for your technical expertise, but sorry, if you are not a violinist or any other trained classical instrumentalist you may not realize that close exposure to real instruments teaches that these natural sounds are BRIGHT (in the good natural sense, not for example in the artificial types of distortion that is obvious if you tune the radio slightly off its freq and get the static which brightens the sound). The microphones in most recordings are close, roughly comparable to the 1st row of the hall, so when most people who sit much further away say that their 10th row sound is comparable to the recording played on their systems, they don't realize that this means their systems are rolled off in HF especially. These listeners would be astonished to go to the 1st row, or better yet, stand on the podium to hear what the conductor hears, which is the most detailed and balanced sound of anyone in the hall. This sound is bright and brilliant, not at all like the sound of most tube equipment. I have an open mind to discover some tube electronics that are brilliant and detailed. On Jay's thread, "My long list of amplifiers..." he plays his new tube mono amps the identity of which he hasn't disclosed yet. They sound brilliant and bright, and he says they are more detailed than many SS amps he has owned.
My 60 years of playing the violin, the latter 50 as an accomplished performer in solo concertos, chamber music, orchestra, and 50 years of being an audiophile and correlating audio system sound with live in all sorts of venues and environments, qualifies me to make the statements in the preceding paragraph.
