Features and specifications will be posted with the preorder announcement. We'll leave subjective reviews up to you guys.
Channel balance is the amount of error between the left and right output signals (i.e., does one side sound much louder than the other?). Any amplifier which relies on an analog potentiometer will exhibit some degree of channel imbalance at the lowest threshold of knob rotation. That imbalance can be severe until you turn the knob past the imbalanced region, usually the first 10-20% of knob rotation.
Analog potentiometers are low cost and perform well--as long as you listen at volumes above the imbalanced region. Implementing a digital volume control without degrading THD+N is a challenge. Done right, it's worth the expense.
OMG I'm not CRAZY!!!! (well just maybe...) I ALWAYS notice that with almost every device I have ever used. Some better than others, but I didn't know if it was my headphones being louder in one driver or something. So it's the channel balance of the amp! And this is better than the 02 in that regard?
Overall, I really think I'm leaning towards this as my next amp.
