Does the voltage of the BluBOX power supply make a difference in terms of sound?
The BluBOX can be operated with power supplies that deliver a voltage of 9 to 16 volts. There is a minimal sound difference when supplying the BluBOX with different voltages, but this is absolutely marginal: A higher voltage (16V) leads to a slightly crisper sound, while a lower voltage (9V) makes the sound a little bit softer.
