Power Cables and Power Conditioner

I believe you are benefiting from the PS cable. As I stated, with a quality PC vs. stock (I have owned a Rogue preamp so I know first hand), you’ll get better power delivery and lower noise.
My point is that different brands of cable have different sonic signatures;
eg, dynamics, imaging, neutral or coloured. You could audition PC’s by ordering from dealers with a return policy. I’ve tried many.

The Furman fixed PC is fine for low-current draw components. You'll benefit from audiophile PC's, but how much depends on the cable design and the type of component. 
The amp should have a larger gauge cable and typically is not plugged into the conditioner, since it may restrict dynamics.

Re: dedicated line, you run the line inside the house through the wall and under the floor like any electrical. A licensed electrician must do the hook-up to the breakers.
Search the archives for "dedicated line."

OK thanks Lowrider.  I think if I do the power I could go a short distance outside the house and then into the crawl space.

Regarding the amp not being plugged into the PC.  I have read that on here before.  So do people just sacrifice the amp in case they get a surge?

Some people have surge protection for the amp located at the breaker box. I plug my amp into a professional grade power strip which does not limit current.
This Furman is the type used by musicians on stage to power their gear. To my ears, it seems completely transparent and protects against RF and EMI.

When I moved from a home with crappy power to one with good power, my PS Audio regenerator displayed steady voltage and low distortion. I ditched the regenerator and could not be happier.

If your power is clean as you have mentioned (measured?), then how about power outages, lightning, etc.? If all is good, then I would minimize what to throw at your system, but a dedicated circuit(s) is always good for other internal issues. If your power turns out to be crappy, create an "overall" plan of attack based on the circumstances. However, if you live in an apartment, for example, so you can't do much about it, then a fine conditioner may be a good solution.

I'm with Kenny - I had a power conditioner, but found things got much better with good power cables and a power distribution box that had no filtration - just a breaker for safety and some very good outlets on the back. I also plug the amp directly into the outlet, not the distribution box.

A dedicated line with MRI outlets across the board with good power cables into each component is one way to ensure there is little to no noise spread from one component to any other.

Good power cables will actually reduce the effect of digital equipment has on overall sound quality

If there is a thunderstorm - I power down and remove all plugs.
 
Very few conditioners protect against a ground strike, which actually are the more common occurrence and lifts the voltage potential of the ground and neutral wires to insane levels. So you think you are protected when in fact you are not

My neighbor had this happen and it wiped out everything that he thought was protected - than goodness for house insurance!
