Cheers guys
A Interesting experiment this evening I disconnected the Mainline which I had been using for preamp duty, I wanted to see if the ACA would have enough gain to run straight from the 2.5v output dac for headphone use and it was a great success with the HE6 sounding simply the best I have heard so far. Both my HD800 & T1 also sounding very nice and I now have no noise all is dead silent (Mainline transformer perhaps). I am controlling the volume using the volume slider control on my media player which isn't ideal but hell the HE6 are really singing and its got me thinking about incorporating passive attenuator in the enclosure maybe relocate the led power switch and have a passive volume attenuator in its place.
