There are members here, who have experience behind the glass in a studio.
Those ears, are maybe the only qualified to comment on audiophool "sonic truth."
"Absolute Sound".... whatever
Putting together a setup that pleases one's ears is the goal-IMO.
"Tubes color sound as well."
If you listen to pre 80's recordings, there's tubes in instrument amps, possible vocalist mic preference AND studio that contribute to the actual sound of the recording. Why would tubes in the playback equipment attempting to reproduce it "color" it in a less convincing way?
