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.

Rok2kid - I guess you're correct. There is no actual dirt in there, but there is something going on in the power lines that the Audience power conditioner appears to rectify. At least in the case of the power coming into my home. Makes quite an improvement, IMO anyway.
I think most of the advice being offered in the post is close to useless. People are talking about their particular experiences and the products they've tried. In all probability each experience is probably so unique that no valid generalizations can be drawn.

Would you recommend the same solution to someone living in a rural area with little or no industry as you would to someone living in a 300 unit apartment complex located across the street from a major medical center?
'61, this is Audiogon! ya take what you like and leave the rest...most will find a recipe that works, don't ya think?
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.
