Awesome! That speaker sounds like its awesome. I think an all AGD system will be amazing, esp HE1. I feel he9 review is amazing preamp and he1 is likely better. Even the master 1 which is a step down from HE1 was in the same league as the far more costly CH precision.
Kingwa's R7HE Dac is really well regarded as being excellent so its worth considering. And also think about the AGD Di20HE digital interface that thing is amazing.
