Thanks @johnjen for fielding the questions. I am going to reiterate that the system pictured in post 58: http://www.superbestaudiofriends.or...tem-synergy-special-sound.54/page-3#post-8918 continues to enchant my musical enjoyment. Possibly more than the Ygg/GuMB ZDSE HD800. No signs of listening fatigue or getting bored after many hours of listening in every session. If anything, hard to put the headphones down and come back to reality.
