An essential feature for me in a linestage is well implemented support of balanced inputs and outputs. By "well implemented" I'm looking for low output impedance and, if possible, galvanic isolation of the outputs such as via transformer coupled outputs. Since I like the capability to bi-amp, having a volume control on one of the outputs would be a great bonus. Even if you don't need these features right now, these may be something to keep in mind if your systemm veers in that direction.
Another overall system requirement, again for me, is the ability to reverse absolute phase on the remote (and yes remote control is a must-have for me). Ideally, this would be provided by the linestage, but failing that, the DAC would have to provide the capability. In that case, however, you're left without the ability to remotely switch polarity for non-digital inputs. The impact of absolute phase has become more important as my system has evolved.
I'm also evaluating linestages and appreciate all the input to this thread.
