They also have been some changes cosmetically & sonicly since the international meet ,all for the better & some where listening though my Maxed ES-1 at the end of the Ny meet.They sound good but are not at the HE90 level,but neither is there price.
I am in the plasma camp,I have a 42 panasonic in my bedroom,& will eventually replace my 35xbxr Sony in my living room with a Pioneer 50inch.I Find the Plasmas look more natural to me.Looks good from any angle & no motion blur.
Dared vp300 amps sound very good with the Duos,Heard my pair on a pair of duos at a audiocircle Rave.No preamp needed as they have thier own volume control.
