I have recently purchased a P5 unit for my headphone-based audio system (PWT => Matrix Sabre-X Pro DAC => Vioelectric V281 headphone amplifier => HiFiMan HE1000 headphone).
These are my power input values-:
Voltage = 123V
THD = 1.8%
These are my power output values (with the default MW strength setting of 4)-:
Voltage = 120V
THD = 0.1%
Load = 7%.
My question-: Is there a theoretical reason to choose a MW strength setting of 5 or 6. What difference will it make? Can the P5 unit register a THD value of <0.1 % (eg. 0.05%)?
