OK, the D400s arrived today. I upgraded to firmware 10.0.2, as recommended by the dealer. Set it up to play through USB from my Logitech Squeezebox and stream music from my Vortexbox Linux server. Driving a pair of restored Quad ESL-63s.
Sound can only be described as sublime! Beautiful refined string textures. Stunning but entirely natural dynamics. Midrange of the Quads taken to new heights. Sad that Peter Walker is not here to witness the full realization of his marvelous speaker.
The Quads have vanishing levels of distortion over the full frequency range, below -70dB from the lower bass to the high treble. They are phase true, and can easily accurately reproduce a square wave. With the D400, they are taken to new heights!
Here's a pic to illustrate my 2nd floor listening room (it's a large room of 18' x 28' by 15').
