ERS may be part of their tweak toolchest, but it alone cannot explain the dramatic improvements they can obtain on typical units. I have used ERS extensively in my own tweaking activities, but I could never get my old CD players to sound like my TRL Sony 2000ES.
Quicksilver only takes 72 hours to settle in so it is not a major contributor to the long break-in period.
My now modified Marantz SA-14 unit is being shipped back to me this week from TRL. I may pop the cover out of curiosity to see what it looks like inside, but in the end my interest is to just enjoy the music, so I won't obsess about what they actually did to the unit.
