Hi-Fi'er:
That's good to know. Makes sense that they're selling the old ones off cheap to make room for the new ones. Must've been a miscommunication with the Aune rep I was chatting with.
So now you've got a choice... Buy the old one, put a dot on the volume knob yourself and put up with the higher output impedance, higher Low Gain, and slightly worse channel imbalance OR wait for the new one.
If you're using a DAP with variable LO, that basically solves the high Low Gain and channel imbalance issues. However, you're still stuck with 10 Ohm output impedance. Depending on your gear, none of these may even be issues.
So whatcha gonna do???
