That doesnāt work anymore after a while
So to just do a bit of a rewind and not get too caught up on adding a balanced supply transformerā¦
My system sounds absolutely epic. Using Nordost Tyr 2 into Musicworks G4 block. This goes into new 32Amp 10mm dedicated mains supply.
Then only the 4 power supplies are used into that block 552DRPS and 2 x 555PSDRs. And the Linn Klimax Radikal 2 using Puritan Ultimate cable.
The 500DRPS goes direct to double socket on the dedicated mains supply.
The router and fibre broadband both have SMPS. These are on wireworld Matrix 2 fed by Naim powerline into ring main.
The SACD player and Farad Super 3 and Phoenixnet are on the Puritan 156 with 4m Ulimate Puritan cable into dedicated AV 20amp 4mm radial circuit.
So a division of power.
Going for a balanced mains transformer is going to be a difficult installation as it will need to go outside.
I am really not sure if it is worth the hassle for a bit of hum occassionally?
Itās not top of my list of things to do, put it that way!
The system sounds absolutely epic! The Nordost Tyr 2 is a ligjhting star in the recent changes!

Its not just hum mate, if you think that your cables and mains block are doing good stuff then a balanced supply will certainly be even better, as it does it all naturally without getting in the way at all.
You wont see a puritan cable or mains conditioner thingy or anything snake oily in any way in a studio or anywhere else if you require clean mains. They all use balanced supplies, end off.
It surprises me not more use it, i know lots do, i guess manufacturers would rather you spend Ā£1000ās or tens of thousands on cables, mains blocks, etc, etc, rather than Ā£500 to Ā£1000 on something thatās guaranteed to do what it says on the box.
Anyway thats how i have found it to be.

I have to agree with you. Balanced is the way to go in my opinion.

Agree,the easiest way to make money in the Hifi business is to sell cables etc.

It doesnāt need to be difficult at all. Two 3KVA balanced power supplies, one plugged into your 10mm feed and one plugged into your 4mm radial feed is all you would need. At a total cost of Ā£1100 from Airlink, no need for an electrician, no mess, no fuss. As @Dunc and @Hifi_Naim_CNNL have attested, it just works.
Mains leads are then used in the same way that interconnects are used, to fine tune to the sound that you like. I use Vertere Redline on all my boxes because they open up the sound the best out of all the different leads that i have tried.

This makes the most sense as it would be very difficult now to hardwire a larger Airlink BPS transformer, say 7500VA into current set up.
2 Airlink BPS3000 MPUK make sense as my voltage is 243 to 245. The MP range they make means you can adjust rhe incoming voltage.
Do the Airlinks make any noise at all?

The BPS3000 MPUK is the one i have. Once you have the voltage set correctly the BPS only emits a very low hum, i have to have my ears very close to it before i can hear it.
As a sidenote, if you can give Airlink an accurate average voltage for your house, they will make the BPS to that voltage. Something worth considering, i donāt know if there is an extra cost invoved though.
With three outlets to each BPS you can of course plug in any and all of your blocks. Donāt plug in any SMPSās though

Hi Dan,
Also worth a chat with Naim about voltages.
My NAP135 boxes still had low level hum at 242V, so I dropped the BPS output to 230V and all humming stopped. This was after checking with Naim first.
Best regards, BF

@Dan_M , why dont you get those thatās from the main? Not from the DB? Isnāt it easier ? 
am reading up on balance power supply (plixar) as itās from Sg .
I wonder how much help it can do to the system . So I am reading, getting as many infos as possible is important before I contact plixar .
Very interesting. Should one only power the source or amp or both ? That requires separate supply boxes too ..
One 3KVA BPS can supply everything, amp, preamp, sources and any good LMPSās you have.
There really is no need to go spending Ā£6000 on a PLiXir BAC 3000 though. Apart from looking pretty on the rack, there really is no difference in what it does to an Airlink 3KVA BPS. All BPSās work in the same way and all of them have the same effect on an audio system. In fact, and this may surprise some people, they have an enormous effect on very very cheap systems.

My region has no airlink 
This is actually not true. I had both the Airlink 3000 and the Plixir BAC 1500 MKII at the same time for about three months. The Plixir was better by quite a margin. I then sold the Airlink.
The Airlink is still very good though.

Seems much easier to make a wooden plinth and sell it for 40 years
I donāt know about Airlink but once considered the Plixir Elite BAC. However I went with the Furutech instead as the Plixir is too costly. Nevertheless, Iāll likely consider the Plixir in the future if I move to a new place.
If Iām not mistaken, high quality (usually costly) mains power cables are reported to make a difference with the Plixir balanced power supply either from wall to Plixir or Plixir to components. The Plixir owner or designer provided upgrade options for the mains power cables if you check the website.

have this small issue .. I need to use my nordost QB . I womder how beneficial it is for me , not gonna use directly to my boxes etc, unless going through my QB is less effective , and not altering any sound , then thatās possible for me. If I am to go direct to my QB, I only need one point .
Yes they have their own power cords , both C13 and C19.. the box is big and very heavy . Can go up to 50 kg.

So with the Airlink BPS3000UKMP each has 3 sockets off it. So I am thinking this:
No. 1
Separate Mains 32 Amp 10mm double socket > Airlink BPS3000UKMP >500DRPS, 552DRPS.
No. 2
20amp Radial 4mm. Double socket > Airlink BPS3000UKMP > 555PSDR, 555PSDR, Radikal 2.
I can run switches and CD players off a block like G4 or Puritan 156 off the Airlink No. 1
SMPSs on Ring main.
What do others think? The 5000 VA hardwired units are not practical for my set up with no convenient space without redesigning the newly installed dedicated hifi mains.
