about to jump into the power cord foray


I am about to jump into the power cord foray. Since I’ve upgraded my IC’s and speaker cables most recently, I think the next step should be to look towards replacing the stock power cords. My system is as follows:

Dynaudio 52SE bookshelves
McIntosh MC2105 power
Audio Research LS-7 pre
Adcom GCD-600 cd changer
Lite Audio DAC 60 dac
Rotel RT-1080 tuner
Audioquest Diamondback & Kimber Hero IC’s
Kimber 8TC cables

I intend on putting IEC sockets on the A/R, McIntosh, and Adcom in the next week. If I could find a high quality changer, I’d probably dump the Adcom but I haven’t seen anything that’s really in my price range. Since I don’t have a new power or pre amp in the budget for the next 2 years, I plan on adding IEC sockets to the aforementioned devices. Will I notice any sort of improvement in sound quality, by going with Signal or Element cables with my current equipment? If not, should I look at a cable in the $100-150 range like the Virtual Dynamics Power 3 or VH Audio Flavor? I’m also open to any used cables on the site in the sub $150 dollar range

Blindjim some assumptions that enter into this;
First there is the assumption "everyone" has a system revealing enough to hear a difference.
Second" everyone 's" hearing is anatomically able to hear the differences.
Third " everyone" wants to hear more detail, dynamics etc.,
Blindjim, while you make some very good points, I think you and Musicnoise are talking about different things.

You're 100% right when you talk about personal, subjective things like attraction, favorite foods, movies - even your favorite song or musician.

That said, the ability of a piece of AV equipment to work properly is highly dependent on objective electronics. For example, we can't deny that a CD player's ability to accurately retrieve and convert the data on the disc depends on it's specifications.
Whether we "like" the resulting sound of a particular player is a different matter; most of us are aware that the many combinations and arrangements of components in a CD player/amp etc can affect the sound in a way we might like or dislike, but it still has to adhere to basic EE principles or it wont work.

The trouble with PC's for people like Musicnoise and me is that they are not complex electronics; they are just copper wire with a plug on each end, carrying raw mains voltage to your hifi's power supply, and don't carry complex signals like speaker cables and IC's.
To me it's a bit like thinking my car will run better if I use the gold-plated gas bowser hose instead of the rubber one; as long as the fuel gets from one end to another unchanged, then the car will go as intended.
my advise is to try a mid priced or low priced model from one of the internet vendors that offers a trial period. If you hear the diff, great then move on the experimenting between brands. Try voodoo, signal, element etc.

If not, return it, your only out the price of shipping...
The item at hand that I take issue with is the one wherein a person says adamantly, “… it’s the numbers only which matter’ in determining good from less than good, or bad… or better for that matter.

My own background says nearly the same thing mind you. Some eight years ago I would likely have sided with Musicnoise completely. I’ve since found out otherwise for myself… and much to my shigrin in some cases. I’d not wish to restrain another from some greater experience either.

I doubt too many of us are looking at possibly suspect specifications at point of sale.

All of us need to find these things out for ourselves and in accordance with what ever level of gear or satisfaction we wish to attain.

I thought much of my notions to be not so much assumptions, but as commonly accepted pre-requisites…. Resolving system, and good hearing need be had right up front.

For instance with either of my two receivers, only one shows greater sensitivity to power cable exchanges, the Sony es. My Onkyo TX SR 805, on the other hand, has less responsiveness to power cable swap outs, though it does afford changes in the sound … just to a lesser degree. With it only my most expensive cords seem to show improvements. Therefore I don’t have to spend much on it as I’m unable to justify the expense there.

On the bench side of this issue let’s take Stereophile reviews to task for a second here… JA does the testing usually. A review of the Audio Physics Virgo III shows it’s numbers were well, far less than good on the bench, but translated very well during listening sessions, defying the numbers JA revealed.

Most recently, JA said the Bel Canto DAC 3 was the most accurate DAC or was it component, he had ever tested. Yet, he holds onto the Benchmark DAC instead… and I feel if JA wanted the BC D3 he’d be able to get one, don’t you?

One last point… I’ve spoken with at least one cable maker for some years now, off and on, and given his experiences with cable cobbling, he says he can see a cable on the oscilloscope and determine what it will sound like before hearing it, but in the final analysis he withholds his judgment for the listening sessions. I suspect he is not alone in those exercises.

For the greatest percentage of us audio hobbyists, enthusiasts, and flat out nuts… the listening session (s) are in fact our ‘final analysis’. Our own personal measuring tool. Consequently I hold fast to some precepts which have served me pretty well these last 8 years now, one’s I have learned from the good people here at A’gone, and proven to myself here at my home and at dealerships where applicable.

Basically, I’ve found everything can and usually does make a difference. Isolation, cabling, power conditioning, tubes and sure, the components too, all add up and are integral to the end result. Replace one thing in it, or if one thing is not acting as before, and I’ll surely know somethings up immediately. Somethings less, somethings more so.

And just for the record here, ALL my own listening – testing sessions are done in the ‘blind’. It ain’t all fun either. No pun intended.

System resolution of and by itself will aid in determining these ‘differences’, knowledge and experiences, will assist in deciding upon, ‘what’s really better’.

On my PC system, and a lesser degree my BR HT SYSTEM, all of my CD’s can be played there with great results. My main system is a mite more picky. Well, it’s lots more picky truth be told. Poor recordings are shown up there for what they really are, poor, very easily.

One gets in where they fit in… there’s little sense in my own mind to place for good and all, a $1,000 power cord onto a $100 source. Or spend thousands on cabling for a $500 receiver or integrated amp with bookshelf speakers. That being said, there’s someone somewhere that has done just that.

So my own designs on system building aside, the hearing is the true decider. The final analysis. Why you will pay more or less for anything in audio.

To not try however, or be contemptuous before the fact only limits your own exercise. Keeping an open mind and acting with some degree of prudence opens many doors. Prejudice closes them all.

I really do enjoy very much so, all of the rigs I have, just on differing levels of performance. Just like I used to really dig my first 125 cc dirt bike, but it didn’t compare to my drag bike.
Blindjim, that was eloquently stated and your patience factor for trying to explain this segment of our beloved hobby of ours to people locked into their narrow roads of "safe numbers" is very admirable but I'm not optimistic anyone will likely be reformed on these threads.... although years ago I was so intrigued by all the talk about powercords and what they could do, I had to give it a try. Formerly I was adamant in my mind that there was no way they could make any difference. Today I am so grateful for the immense rewards power cable swapping and matching have done to custom tailor and DRAMATICALLY improve my system that anyone who says it can't make a difference is simply wrong. It does make a difference. Different brands do, different sizes do, different materials do, even different male and female plugs do.... Iggyminn: I would start with Signal Cables MagicPower power cord on receiver/pre-amp and/or power amp and a Magicpower Digital reference on your CD. These are all excellent values and amazingly better than stock cords. You have a 30 day trial with all of them (and you should give them a good 50+ hrs of break in)but there is absolutely no way you will not hear a significant improvement over what you have. Period. From there you might want to work up to the VH Audio Flavors and there's much more after that as your system and its resolving power evolve. In trying to stay as PC and inoffensive as possible I will finish simply by saying "If you consider yourself an audio enthusiast and own a reasonably credible system and can't hear an improvement between typical stock power cables and a decent (or better) aftermarket replacement, you should probably take all the $$$ your saving on not buying them and consider expanding your interests down a road that fits your "safe numbers" a bit better. What about croquet?" Happy Lissn'n
