2x555DR vs. 1x555DR on a ND555

In the summer i’m going to demo an EVO3 Super Titan… should cater for all my needs including removing DC offset.

Gone from two 555Drs to one and don’t miss having the 2x too much…
Using the second one in the second system temporarily…

That’s what I like to hear.

Just kidding. The second psu is back on and going nowhere. I better find the funds to pay the credit card. 0% financing only lasts so long. :slight_smile:

As the discussion went a bit into power distribution. I would argue that I don’t understand people who have a 2nd ps but haven’t got a top end power distribution solution. As you loose so much in mains supply…, which you can not win back anymore.
I have the Ansuz power distribution and power cable…, while there are other good solution as well on the market.

And as to the original topic. The 2nd supply brings more naturalness to the sound, more easy, better soundstage and more mature bass. It was an upgrade I didn’t regret.

Does Ansuz power distribution is good for Naim devices? Naim does not recommend to use surge protector or any filtrs

On the power distribution front, I thought the Powerigel was as good as it got, never having hear anything better, including the Powerigel Plus which was disappointing, lowering the noise floor but also losing textural detail However the Sean Jacobs (Custom Hi-Fi Cables) Powerblack block comprehensively beats it with a very similar design at a lower price. It is also built to order and can therefore be configured to have as many leads as you want, avoiding trailing unused leads.

Hi Meni. Yes it is totally ok. And Ansuz doesn’t follow the approach of the other suppliers which are doing some odd things on conditioning. If Naim itself would recommend it, I don’t know. But I have the stuff also from my highly regarded Naim and Linn dealer.

Hi I have one 555ps and decided to take the Russ Andrew’s challenge and upgraded my mains power leads to Powerkord Evo 500’s wow big upgrade . … more information better stereo…well better everything…no negatives. This is allot cheaper than a second 555ps. Probably the uplift is not that far off a 2nd supply…also I am seriously struggling for space…so this option made sense… Of course god knows … if you added the Powerkords to 2nd supply it would be amazing…

Did the Powerkord Evo 500 replace a PowerLine?
Interesting upgrade, specially considering it replaces a second 555PS !

Mostly I had one heavy duty home made job…the others powerlines … there are people who have replaced powerlines… according to Russ…all reporting excellent results. The lead has a different design approach … being kimber woven. I was sceptical so took them on a 60 day trial. All I can say is they are not going back…been in 3 weeks and they are getting better and better…awesome.

My system is not optimally stacked…out of necessity…I think the noise rejection really helps…for me.

I suggest you try them … you can always return them.

Of course slightly off topic before getting 2nd supply make sure you have a good ethernet switch…I used the Aqvox SE … a really big upgrade… :+1: There are several alternatives…EtherRegen…etc

My system has been transformed with a Unifi Switch and Unifi Dream Machine router.

The change in switch …did things I could not understand … the bass performance…was transformed from good to omg…texture…and you can almost sense the thwack on the drum skin… of course all the other usual upper frequency stuff was also improved…

Are there any feelings/thoughts on the powerlines here.

Primarily I’m wondering if the plugs (either end) are decoupling properly especially if 3 pin socket end does not have the cable dangling freely - I guess the IEC socket end would be like the 3 pin end when connected to a device direcvtly instead of vertically down into the strip.

I sarted thinking (perhaps too much) about this when I tried some ISOL-8 power blocks and mains conditioners as - the 3 pin powerline plug was upside down in the mains conditioner (as the sockets are) which I didn’t think was ideal for the powerline itself. With the mains block the IEC end of the powerline went in vertically as you show - again I wondered if it worked optimally.

It would seem a few regard these WireWorld blocks as good value and performance - they seem reasonably priced too, may well be worth a shot in my lower end setup.

I use one in mine too - I like it for a clean presentation and non-muddled timing and lack of smear - once you figure the plug-in sequence that does that.

I plug my power Amps direct into the wall as they do not like being on any block (the rest of the HiFi like being on the WW block vs wall) I’ve tried and just go fat boomy and flabby bass if not on wall sockets, but I figure that is because they are the only bit of HiFi not running class A and demanding a high dynamic current correlated to the music - none of the other HiFi boxes is doing that so have different possibilities for use on blocks and daisy-chaining, etc.

I did try one far more expensive power block a few years ago that everyone rated and liked as an upgrade from the Wireworld block - in my system at that time it sounded very poor and blurred all into a mess and lost the point of having an Active system so I rejected it.

Probably a more careful investigation may give a better result than I have now - I do think that is very likely and aim to try some blocks again - but will keep the Amps into the wall sockets as I already recently heard on a friends system recently that when he plugged the Amp into the very expensive power block it was (for me) unlistenable with bass all over the place - then put into the wall and tight bass returned.
That may be down to resolution of low bass with the speakers used too.

Thanks DB - I saw your mention of that block first - ordered one last night.

I tried an ISOL-8 power conditioner some weeks ago and the system sounded rather polite/refined but lacking in energy and drive, rather lifeless really - I did wonder if using 2 x NAP 250s was too much for it as it all felt too constrained/constricted.

I’ve not heard a Power conditioner not do what you describe.
Power blocks all sound different but conditioners - where filtering is added - always spoil music for me.
I think some Designers forget current flows both ways and you are not just keeping-out dirty mains noise but also that the HiFi rectifier generates enormous HF noise - and it has to go somewhere - where will it go if the conditioner does not allow it away from the Amp?
A filter blocks by presenting a high impedance at certain frequencies and then current flowing through at those frequencies are turned into larger noise voltages - ways to manage-away these noise voltages and consider all the HiFi mains connections as a mesh circuit will get you further.

In any case listening to things informs if it works. :slightly_smiling_face:

The only thing I would consider is a huge balanced mains transformer…airlink do one that’s about 15kw!!!

Quote: “Block (Wireworld Matrix 2) has mains-in via Powerline left - then empty, empty, S1, 555PS(A), Empty, 555PS(D) right.”

Hi @Darkebear, thanks for this. I have a WW Matrix 2 currently idle and curious to give this a try. I have a spare PL I can feed the block with from the wall. I have a single 555PS on the ND555, 552PS and 500PS all with a PL each. I also have PL Lite feeding the Klimax Radikal for Vinyl.
I’m assuming you’d likely recommend:
500 and Linn go in the wall and of course the Matrix PL too, but any particular plugging order for these?
Maybe worth mentioning that the wall mains is 2 double unswitched sockets, (i.e. there are 4 outlets to choose from) which are on a dedicated radial supply circuit that is also on its own phase of a 3-phase house supply.
then:
empty, empty, 552, empty, 555, empty on the Matrix2 block?
Thanks,
Kevin
