I am putting together my Hifiman HE-6 setup.
Can I leave the Balanced Outputs (in the back) connected to my Bryston 4B-ST if I am listening to either Balanced or Unbalanced headphones? I don't mind disconnecting the headphones when using the preamp section but I would prefer not to disconnect the XLR cables in the back.
I will be using the BHA-1 as a preamp into the 4B-ST to drive the HE-6s. However, I really like how the Grado RS1is sound from the headphone amp. The amp section drivers the HE-6s okay but I think I would choose the HE-500s with my WA6-SE.
I am expecting my HE-6s driven by the BHA-1 and 4B-ST to be close to my endgame.
Yes you can leave the rear XLR's connected. In fact the BHA-1 is capable of driving all the connections at once if needed.
