Power Cables and Wall Sockets

@carlsbad that is helpful. So more than likely, the power is mostly impeded by the last leg of inferior IEC cable. It seems almost fantastical that a $5000 power cable would make a significant difference when plugged into a standard outlet. I tend to imagine it being the final ultimate tweak on the highest end systems, but I could be wrong.

I'm curious to experience the difference myself, though honestly I'll consider lesser priced options that the AudioQuest Dragon! Since I wouldn't upgrade all my current IEC's at once, do you have any recommendations for prioritization between a Pre-amp, Power-amp or Sub?

@imaninatural   I know how important it is not to appear to bash expensive equipment, but I do not recommend expensive power cables.  I recommend heavy gauge power cables.  I use 10 awg for all my amplifiers.  I've never spent over $100 on a power cable.  YMMV.

The "wiring in the wall" argument has been debated ad nauseam. What is clear for the person undecided about that argument is that there is a process to decide for oneself. 

(a) Buy a good power cable with a return policy (buy used from The Music Room, e.g.)

(b) Try it out.

(c) Keep or return.

It's really that simple. 

@hilde45 I should have dug into the archives to answer the "wiring in the wall" question. But I appreciate the response and am looking forward to upgrading the cables to my amps to begin and see what kind of improvement that I hear. 

One thing that I am curious about is if upgraded power cables will eliminate the issue of my lights dimming when listening at reasonable high volume.
