Dan's new amp is called the "Relentless" and will be an all-out assault on SOTA amplifier design and capability.
Bill McKiegan was at Definitive's Music Matters last night in Seattle (also there tonight). He was demonstrating the Progression preamp and stereo amp.
I don't know much, but they are said to be 1500/3000/6000 watts each, and weigh hundreds of pounds. Here is a pic of the meter, it is HUGE. I guess it will be unveiled in Munich.
