Plugging Order of Equipment On A Power Strip / Extension Block

Posted by: ryder. on 29 October 2016

I have read about the deleterious effects of power strips that come with a glowing red light and an on/off switch. Unfortunately I am currently using one, an MK Duraplug power strip that has the red light and on/off switch.  The exact model of this extension block I currently have in the system is as shown below.

I will be getting the Wireworld Matrix 2 power strip soon and would appreciate some advice on the plugging order of equipment on this thing to optimise the performance of the system. I used to have the NAP 250 DR connected directly to the wall outlet since the power strip has a long cord (4.0m or 5.0m cord). With the soon-to-be Matrix 2 power strip, the NAP 250 DR cannot go to the wall outlet and will have to go into the power strip.

I have read about the putting the source, considered as the most important component, closest to the socket of the power strip, and the least important component at the end of the strip. However, this was assuming the power amp is not connected to the strip but to a dedicated wall outlet. What if the power amp goes to the power strip as well? I would appreciate some thoughts on the plugging arrangement below, whether it is considered acceptable.

1. NAP 250 DR

2. Chord QBD 76 DAC

3. Krell KPS-30i CD player / transport

4. Hicap DR (feeding the NAC 282)

5. NAPSC

Any advice would be appreciated.

My order would be:

1. Krell KPS-30i CD player / transport

2. Chord QBD 76 DAC

3. NAC 282

4. Hicap DR

5. NAP 250 DR

6. NAPSC

Thanks Robiwan. I have made some adjustments to the original post as I figured out that the NAC 282 does not go to the extension block as it is powered by the Hicap DR.

So, the arrangement based on your recommendation is as follows.

1. Krell KPS-30i CD player/transport

2. Chord QBD 76 DAC

3. Hicap DR

4. NAP 250 DR

5. NAPSC

Cheers.

Do you hear a difference? 

Posted on: 30 October 2016 by ryder.

I have not bought the Wireworld Matrix 2 extension block yet so I have not tried. Just seeking some advice from those who have tried. I remember reading some posts which reported sound improvements with optimised plugging arrangement.

i hope the block doesn't have a filter?

Posted on: 30 October 2016 by ryder.
I am not too sure if the Matrix 2 comes with a filter. All I know is it is OFC Star-wired but I am not sure what does that mean. There is very little description on the technical data of the product on Wireworld's webpage.

I could give you a preferred plugging order, random or experienced, but what relevance would it have to the results you might find doing due diligence for yourself in your room?

I could have a benchmark to base upon. The plugging arrangement may not be something that is based on "preference". Optimised results can be consistent across the board with the recommended arrangement. It's like the stacking order or arrangement of Naim boxes on the Fraim, for instance. 

The "general rule" or recommendation can be helpful, and it can be more useful than doing "due diligence" in some or most instances.

Could you further explain why the matrix has to have the 250 plugged in.

Posted on: 30 October 2016 by ryder.

The wall sockets have about 4 metres between them. I would need a 5.0m length of power cord to connect either the power strip or the NAP 250 DR to one of the wall sockets. I do not have plans for an aftermarket cord that is more than 2.0m in length.

Ryder - on the Wireworld Mateix ou are free to plug as you want. It's star-wired, which means each socket has the same 'priority'. 

Enjoy.

I personally followed Nordost's recommendation coming with their QB8:  Source<Pre (Primary (star) Earth)>Amp.

Hi Adam,

Thanks for that, especially the heads-up on ditching power strips that come with red lights. On the star-wired arrangement which has the same priority, it is interesting that Darke Bear has found the Wireworld Matrix to be sensitive to plug-in order in an old thread below.

You could try contacting wireworld and ask if they can make up a power cable that's 5 metres to connect up the matrix. Then stick with the same arrangement as before.

Posted on: 30 October 2016 by count.d

It's not room dependant and if you're asking for advice, it's not ear dependant. It's always, and has always been source nearest the incoming supply, followed by pre, then amp furthest away. Of course, you're going to receive replies saying "I prefer the power amp closest, as I enjoy a bloated, saggy bass with no definition in the highs/mids", but they're best left alone in the dark.

Perhaps we can leave this reply as a sticky, then we don't have see the same question every 3 days.

Just test it when it arrives. I tend to (for compulsive-obsessive reasons primarily) plug my power amps, then pre, then sources. But that's just me. I didn't bother to test. It all sounds good anyway.

If not planning to get Powerlines in the future, a Grahams Hydra seems a far better solution than a block. It's smaller, cheaper and most of all it avoids the ridiculous hassle of deciding in which order to plug the boxes. And you can order the tail in whatever length you like.

Like Count D I do wonder why this question keeps reappearing. Some say source first, some say source last. Try them both and decide; there is no definitive answer. Though as Adam says, if the block is star wired and not just star earthed, the order should make no difference, though there will seemingly always be those who make things more complicated than they need to be.

i have a couple of grahams hydra cable assemblies -- works well for me.

I make my own,  3x double unswitched MK's.  I tried various wiring methods;  series, star & ring.    I could not detect any difference with star or ring & finally settled on twisted L&N in ring & star on E.     But like you say,  it might be (it is) more complicated than need to be.

I am surprised that the POWERIGEL PLUS never imposed itself as a Hydra type PowerLine star-earthed system. It is not much more expensive than the group of PowerLines it would replace. Your thoughts?

i didn't like the Hydra at all. It made the sound of every musical piece the same, as in overly bright, thin and flat. Returning to the Musicline Netzleiste everything felt in place.  

Sorry for my English i'm Dutch.

Using Musicline Netzleiste Plus with very satisfying results. My dealer suggested this order for a more dynamic sound: 1: Amp / 2: Pre (eg. HiCap) / 3: Source - for an airier sound the other way round.
