I bought a used XPA-3 that the previous owner was not using and he since lost the original power cord. Instead, he gave me a white grounded power cord he had lying around which says 18AWG X 3C.
I thought nothing of this, until I noticed a lower end Marantz receiver came with a much more robust feeling cord, with a higher gauge labeled 2 x 16AWG (2 prong).
Is this cord enought juice for the amp? will this somehow lower the lifespan of the Amp?
I just thought if this thing is trying to suck juice out of a straw versus a pipe, is this detrimental?

18 awg is not enough for a power amp, I would expect a minimum of 14 awg. At high load the added resistance of the smaller power cord will cause a drop in voltage to the power supply, requiring it to draw more current and thus generate more heat. The amp's protection should shut it down before immediate damage is done, but running warmer over time won't do it any favors.

18 awg is only good for 10 amps.. 14 awg takes you to 15 amps.. i would feel alot safer with
14 awg...

Same here I would feel a lot better/safer if you were to use a 14 AWG power cord with your XPA-3. How much the amp will be worked depends on your speakers, how loud to you want to go, etc etc. I say get a 14AWG power cord and not worry. If you are in the NYC/Long Island area I can give you one. I have a bunch laying around.

I just looked at the cord that came with my xpa3 and it's 18awg, in fact my xpa200 and upa500 also came with 18awg. If Emotiva is shipping amps with 18awg it must be fine.
