aune X7S Class-A balance output headphone amplifier (New product )

[crazywipe]

Does anyone here use the X7s + Sennheiser hd 650? I use both in balanced on high gain. I feel that middle gain on balanced is just a tiny bit lacking in juice and high gain balanced is a little too much for 650. Anyone here who knows the best configuration for hd 650 with the X7s

Just use the lowest gain that give enough drive and volume.

Can anyone tell how much voltage swing (Vpp) Aune X7s spits at its highest gain setting via balanced?
