Thanks for all your kind feedback. Currently considering the 430HAD or the Master 11 as an all-in-one solution. Have the LCDX and planning to get HEK later on, but the HD800 is toughest to drive/match so that had to be asked first.
Strictly from HD800 perspective, there was a lot of love at the last two local meets for the Audio-GD NFB-27H, which is a sibling of the Master 11.
