Power cord supplied with Luxman L-509X Integrated Amp

Do you think that a company like Luxman would supply an inadequate power cord just to save a few pennies, having charged in excess of $5000 on average for their amplifiers, so that their reputation would be tarnished ?

If the provided cable can handle 15-20 amps, it is MORE THAN ENOUGH. Do not believe some of the myth you hear on this forum about power cables. There is no sense in it since you are limited by the Romex wire in your home electrical installation.

Save your money to buy vinyl and/or CDs instead.....

Upgrade to Furutech ASAP!!

Jason bourne 52 is 100% correct in both his posts.
Manufacture of boutique power cords , power conditioners intended for audio use and expensive glass fuses are a cottage industry exploiting the placebo effect.

@avitacom,
Agreed!

"Not putting a nice power cord in your very nice Integrated amp is a crime. You are leaving a lot on the table to extract the best performance from it...."

I’ve tried various audiophile power cables on my Bryston Integrated Amp and it doesn’t care what I feed it with. Bryston and Pass have long maintained that there is NO benefit in replacing the stock power cables with expensive "boutique" ones and, based on my experience, they’re right.

I've never had an expensive piece of hifi that DIDN'T come with a cheap looking generic power cord.  Same goes for interconnects.  BYOC (Bring Your Own Cable) is expected.

Oh boy… Audio Science Review militia has embarked 

What is physically happening in the cable that produces a better sound out of the system?

And can it all be measured?

Assuming this was an original US piece, then 2 prongs is all you need, and you'll run into less ground loop / noise problems.

To use 2 prongs the equipment must be double shielded, so that an internal fault won't route the AC's 120V to the chasis.

I still use a shielded power cord however.  This covers the AC wires in a shield that is grounded at the outlet and has no connection at the Luxman for noise reduction.

Most 3 prong cords are not shielded and cheap shielded cords are available on Amazon.

I will start by saying that I rarely use the stock pc’s on any of my gear.
I have a c900u/m900u combo, and several nice pc’s to try from nordost, audioquest, and others.  I found the supplied pc’s were best, just like with Shindo gear.  Tough to say what was different exactly, they just sounded off.  I even asked the importer about this and they also said the included cords are excellent.  He said some liked a aq hurricane on them, which I had tried also. 
Bear in mind that these things are voiced with that cord.  Often a change is perceived as an improvement, when it may not be long term.

Where does the noise come from that gets in there without the shield?
And what is the mechanism that allows it to get in?

Radio. Every wire is an antenna. Do you understand how radio works? Transformers? Same thing.

It sounds like you need to do your homework.

Or better yet, experiment. That is if you do own any audio system.

Or don’t. And instead keep reading and posting in the Internet. If that is what gives you a hard on.

Finally.... someone with a bit of sense.

I have the 509x and tried comparing the stock PC to an Audioquest Hurricane and the AQ gave a better presentation, clarity and depth and therefore was noticeably better to my ears, so I kept the Hurricane....its whatever makes you and your ears happier....was it worth the $$, maybe to some and maybe not to others, simple as that...

There are NOT entirely the same thing…
The majority of antennas are primarily designed as E-Field devices, (at least if we ignore loop antennas for tracking bats and fish).

The majority of ground loop problems are predominantly due to magnetic fields and coupling of those fields.
In fact, in a toroidal transformer there are no/little external magnetic fields… So it is clearly not an antenna

And we have not as, of yet been presented with a clear picture of what frequency(ies) the noise is operating at, we don’t really have a lot to go on in any objective sense.
It is sounds like everything/everywhere is a source and there is a Yoda like “Disturbance in the Force” that is picked up be sentient equipment.

I am not saying the stuff doesn’t work, but when Bryson and Pass say don’t waste money on them, and there is no before and after showing some goodness is happening… then it looks it can be higher on magic, BS, nano particles (etc), and somewhat light on provable facts.

If the OP wants a new cord, then “more power to him”. At least they look nice.

The fact that many people I know swear by them is perplexing to me, but I have not had access to try any for a free demo… So I have no subjective opinion on their effectiveness..

No, that's not at all true. A ground loop - by definition - is two or more paths to ground of different potential. (Voltage.) It is as simple as that.

@cleeds you’re correct sir.

 I have not had access to try any for a free demo…

And yet, here you are. Every day, several times a day

@thyname Well how am I to learn about them and how they work?

I agree with millercarbon. My CAT SL1 sig pre amp have 3 pong in to pre amp but don't conect with any inside. They explain, that make a best sound.

And all components for intenal Japan power cord have  2 pong.
