Power plant and power cords upgrades a real wow?

No, no jaw dropping antics..
The addition of a power conditioner may improve the quality of your sound a little.
Mostly sounding tighter, darker background, better highs.
Plenty of variety in power conditioners out there. same for power cords.
The subtle changes powercords can make can be worth the bother.
I am a fan of Pangea only because the ywere the first power cords I could hear a difference right off.
I use a Furman FER 20I power conditioner, and a PS Audio P600 too.
Pelenty of folks will rave about whatever they have, since it worked for them.
None of that matters. Some of them work in one system, another it a different system.
And it all depaned what matters to you too.
So if you want to try some out. I suggest buying used, then if you do not like them, you can sell them off with little loss.

It is impossible to know what another person means, with 100% accuracy, when they are describing what they HEAR. What does 'tight bass' mean? What does 'bright' mean? What does 'dark', 'fluid', 'harsh' and all the rest REALLY mean to you? Then ask yourself, how do I know it means the same to them. Are we really on the same page. Speaking the same language.

In audio you can only listen for yourself. If you like it, that's all that matters. Any wire 'difference' that people hear on this site is so minscule as to be nonexistent. Esp while listen to music. Which, after all, is the purpose of this gear.

When other people tell you what a wire sounds like, it's like telling you what to 'expect'. And if you expect it, you will 'hear' it. My advice is to experiment with wire if you wish, but just keep it between your gear and your ears. There is no 'requirement' that you hear anything and don't be bullied into saying you do.

I do know this, it won't be the so-called 'night & day' experience that many claim it is. Physics and human physiology says that ain't gonna happen! And they have NEVER been wrong.
Cheers

My experience is limited, but I don't mind passing along the configuration I use.

Power Cord to all components - Used Condition - Zen Acoustic Tsunami - Approx $225.00 each.

Power Cord to Conditioner - Crystal Clear (999.99 silver) Approx 400.00

Conditioner - Equitech, Son of Sam. There are several modles. Suggest you select the wattage rating based on your current total power load,plus anything you are thinking about adding down the road. Note: don't include your power amp or possible future sub.

I have two each dedicated 20 amp circuits which I connect my Prima Luna 5 Power amp into and the other one I use for a REL 305 sub. I live in an area wher power surges or lightning is very uncommon, none the less, I unplug the Amp and Sub after each use. I will add non current limiting type conditioners to each outlet when I can afford to do so or I decide its affordable to do so. Probable similar to the 20 Amp type that PS audio sells with 2 outlets on each unit, or Blue Circle or similar.

This set up wasn't base on Quantum physics or other scientific hypothesis. Basically I bought what I thought was the best for what I wanted to spend. I would say this is a step or two up the ladder from entry level.

I suggest you consider upgrading your fuses to one of the after market brands like Hi Fi Supreme (several Forums here on AG to assist with making a choice).

Hope this may help. I am sure that after reading this, others will have there comments/suggestions to add. There are some AG'rs that do a lot of hands/ears on experimentation and research in making there final decesion. Thats probably some of the best advice you can get. Of course you may be wondering that after all this, did I find an improvement in sonics and did the power equipment add enjoyment to my music listening; Absolutly, was it worth the money; absolutly. Personally I think the dedicated circuits were the biggest improvement, but I am sure that varies with the differences between existing wiring circuits from house to house.

The results you get from upgrading cords and/or power conditioners/regenerators will depend greatly on the weakest link in your system. Example: all those reviews on Audioreview by people who claim Martin Logans or Maggies.....are mediocre at best but power them with A/V receivers. Your components, however, should respond quite significantly to upgrading cords and conditioners.

I have found that upgrading plugs on cords also makes a big difference. Cheap wattgates do NOT sound as good as the Acrolinks, Oyaides, Furutechs, or IeGOs though it can be a balancing act choosing the right plugs. And I've even replaced all my outlets with upgraded ones. The Porter Ports are clean and clear and inexpensive making most others sound veiled. The Maestro outlets take performance up another notch being fuller bodied and presenting a deeper and more developed soundstage.

Keep in mind though that upgrading a single cord, while the other stock cords remain in the system, will only marginally improve your sound. The more cords you upgrade, the less compromised your sound will be and the more you will be able to hear the potential of your cords and ultimately, your system.
