My headphone are the JVC HA-RX700 64 ohm and I have to go up to 1:00pm on the volume knob to get good sound
You are correct until Volt.
V=26.8 at the beginning, how much current can run through resister? I=V/R=0.057ampere. So your headphone port has maximum 0.057 ampere, if you drive a 600ohm headphone, you get P=RI^2=1.94w. that's pretty high power.
@Pixelsphotopro, you can replace the resistor yourself like many people did. You can also build a resistor box that can link your cans to speaker post of receiver directly. Your HK pm655 can drive most phones.
