Hey there, Audio GD is offering a new powerful all in one setup from early this July. Master 11 seems originate from master 7 and master 9 based on A-GD description. 9w@40ohm(class A) and 4 pm 1704 UK from Texas instrument. It looks like pair well with my he1000. A great bargain for he560s/ LCD series and even Abyss. My master 11 has been shipped out today. I will post impressions later when I back to state.
