dave_b,
Loudness button reminded me of my intermittent and unnoticed questions on these threads. People get into fierce arguments about tinniest pieces (for example, fuses), or directionality of wire, or taking covers off the component. They argue about perceived benefits and other camp makes just the opposite claims. Not once have I seen arguments about tweaks/tuning include how loud the music was when played with a certain tweak/tuning. Actual loudness is probably one of the most noticeable tweaks a person can do. It changes whole perception of sound in seconds or less. Some allegedly phenomenal cable that makes difference may not be that phenomenal at the different setting simply because ears/brain may not perceive the change it is supposed to make that noticeable. From what I understand, loudness button acts exactly on one part of that (brain), if not on ears themselves. Whatever it is, I often like it.
