I have been reading up on the new Gold Note PA-10 amp and it seems to have some very interesting tech and big power numbers from a none class D amp (of similar size to a class D). Tthe size is the same as the PH10 phono stage. I've seen pricing around 1300 euro so very interesting indeed. they even list a 2ohm load power rating of 300wpc. 75wpc into 8ohm 150wpc into 4ohm. bridgeable to 600wpc.
