Power plant and power cords upgrades a real wow?


I am at the point where the only things I haven't upgrade or to call it some way the weakest links on my system are related to power.

I have Luxman 550 A2
Harbeth C7
PWDAC ps audio
AZ hologram cables
Nordost LS XLR RD IC
Rega P5
Ps audio Phono

A friend came over and said what are you doing with this great gear and with belkin power supply multiple connections and stock power cords in all your units?
I have been thinking since them about his comment but I would like to hear from you guys the true and your experience trough this path.

I am planning to spend 2k on power related upgrades, help and guidance highly appreciate know anything about it.

Regards to you all.

Onhwy61 - you're absolutely correct. Giving audio advice is akin to the fable about the blind men and the elephant -all of them were correct but still wrong. I agree 100% that any component sounds the way it does within a particular system in a particular room and that's it. Put the same component into a different system and the deal's off. The only way to know if something's going to work is to try it in your system. So now that we agree on that, how can we remedy the problem?
Onhyway, your comment is apt. This is exactly why I said, " I don't think you can generalize on this stuff." My comments were intended to be a guide to an approach, as well as an account of my own experiences. This is really a tough area to give good advice. It is really a trial and error thing, because one doesn't always no if one has a problem that can be mitigated by a particular piece of equipment.
Also, let's remember, the OP had no problems with his gear at all, UNTIL, a friend told him he had a problem.

Sometimes, not only is good advice difficult to give, it may not even be required. Don't ever let anyone outside your family listen to your system. Don't worry, be happy. It's all good.
Cheers
Your friend is right because garbage in results in garbage out. The best solution is a separate ring mains from the junction box followed by a good multiplug a la Acoustic Revive Rtp-4 and good mains cables a la Acoustic Revive Power Reference or upper range Nordost. I suggest you also punk down for some good fuses: Furutech as well as Hifi-tuning work wonders. If you want to go further you can apply WA power chips or various forms of ground reinforcement such as Acoustic Revive Rgc-24 and/or Audioquest Ground Control.

In my experience cleaning up the power yields bigger benefits than buying new equipment
