All good progress Ronin.
Thing I am asking is why change the Bose amp? Just having my first proper experience of the Bose in the D2's and I dont see what the issue is? I prefer a bit more treble in my listening but that could be due to my hearing
I see statements on forums the Bose is S#$%. But have not found any definitive reasons why. I do think it can be a bit Boomy but reducing the base alleviates that. Test for me is comfortably numb (live from the pulse album) and it still send shivers. It also makes the rear blind rattle though
