Probably single. But beware of generalities!! The optimal quiescent current is NOT the same for all amplifier circuits. While I would not go so far as to say the factory setting is always best for your particular circumstance, it is likely to be very close.There is some rather poor advice floating around the web to the effect that you can improve an amp's sound by increasing the bias setting. This may be true in some cases. It is also true that you can degrade the sound by this means. With a bit of negative luck you can even damage or destroy an amplifier by increasing the bias setting.
If you don't have a schematic in front of you, and understand it, and understand why the factory sets the bias the way it does -- it is best to leasve it alone. If it ain't broke don't fix it!
BTW, contrary to widespread belief, there is often quite a bit more wiggle room around the optimal setting before any degredation is detectable either by instumentation or by ear. We should be greatful for this since at any given instant the majority of class B (or AB) are operating either slightly "under-" or "over-biased" simply due to operating conditions, component drift etc.
