Understood.
I think it will be possible to cover the whole downside of the digital board with ERS, cut out the transformer holes and put those pieces on top of the transformers.
Regarding Bridge II, it’s enough to cover the chip you mentioned on the child board, not the whole big and small bridge board, correct? I’m still aware of your other recommendations…but nothing around the internal PSU and AC inlet stuff?
Well it seems ERS is meaningful for chips only, not for other electronics.
Very nice 
Hi tony22
The fit is snug for sure but no problems getting it all in there. I like that the size of the Transformer large I know possibly shields a direct line of site interference from the supposed electrically noisy display. Sorry I only took an assembled Pic on completion.
The transformer is more than needed being 60VA and shielded, I wanted the biggest transformer which would fit for higher magnetics, custom wound yes, and the Primary voltage can be chosen 115V. To help me get a perfect fit inside the case I used the transformer mounting plate as a template to align holes as I drilled. (first of all I put the mounting plate “template” inside the DAC case in the position I want, then drill one easily accessible hole with the bracket in place pressed hard against the bottom plate of the DAC. I then flip the DAC over and with the mounting plate in hand I align to the made hole and pop a screw through for good holding align the plate as you want using the rear side of the DAC as the guide to good alignment and proceed and drill the next easy hole and place another screw to hold, I do this for each of the 5 holes. A similar method is used for securing the regulator but I did not use the regulator to brace as I drilled the holes). Other small procedures used to get exact alignment were to use a very fine hole punch, do a small tap in precise location and make a pilot hole I only did this for the mounting plate centre hole as the drill bit required for the hole was big. I did centre tap all holes for accuracy but no pilot hole for small holes.
I don’t recommend exactly the way I did this job, but I left all circuit boards in place when adding the PSU using a slow turning drill the metal fines can be controlled and not sprayed all over the place, I vacuum each hole area after drilling. For me no metal fines got onto circuit boards. If you trust yourself doing so that procedure worked for me, however I would recommend pulling the digital and Analogue boards before doing this work really

The Edcor Mod personally I would allow 3 hours strip down the solder and resemble I performed the job painstakingly slow also ensuring I had all the right tools including an electrical pump solder sucker striving for minimal heat time on the PCB I would say the PCB handled a good amount of heat. I professional would get this job done easily in 1.5 hours I preferred not to rush.
I’m not sure what you mean by external mod, if you mean the PSU I would allow 4 hours. Once again very a slow time and for a tea break while performing the job, no rush and well thought out moves means no mistakes, double check all actions right expected voltages. I professional would also knock this job out easily in 1.5 hours.
A professional is someone in the trade and also having done these modes, if the professional hasn’t done these mods perhaps, they would need another half hour of time.
With all the years of ownership from the original PWD DAC 1 following the upgrade path I don’t plan to sell the DAC on. Locally our distributer in New Zealand wont take back the DAC as a trade in even if it hasn’t been modded as such. The only course of action we have available is to sell on the secondhand market. Quite franckly the DAC has become so good sounding I would not want to sell it and I would listen to the MK11 in home comparing before purchasing.
@ oddeophile
I really like the interaction I got from Michael at MPAudio he is very approachable and answers all questions. The speed of reply depends on how busy and I’m on the other side of the world compared. I considered the cost for a custom transformer to be very reasonable. I have been surprised the DAC seems to be operating at cooler temperature normally placing my hand on the front face late of the DAC it would be reasonably warm it is definitely cooler I will remove the rear bridge cover and fire in a temperature probe at some stage to get more of an understanding. Setting out a custom secondary voltage and amperage for the Audio board was the key I guess achieving an efficient regulator - low waste of power.
Having a P5 powerplant I can guarantee the incoming voltage on the Primary 230AC so I have a secondary at 10.8 volt’s to feed the regulator SLS-HPULN PS.
@ adimon
I’m not the best with words to explain in detail the sonic attributes but could try to give in practical terms before a description, having lived with the Edcor Mod for some time I was blown away with the Edcor Mod, thinking it provided more of a sonic improvement compared to Sunlight (but then the Edcor Mod would not sound as good as it does without the addition of Sunlight. It is always the sum of all elements right. In my system, I got more sonic improvement from the Edcor Mod. Now with the Edcor Mod and Sunlight in, and recently having done the Audio board PSU, I would place the order of sonic improvement with the Edcor Mod and SLS-HPULN PS regulator with transformer to be equal with Sunlight next.
With the Edcor Mod and Sunlight in place then putting the new PSU I hear more
I’m hearing instruments and vocal tones with increased intelligibility, there is more depth and tone to sounds, improved Bass, mids and highs. The improvement is across the frequency range, I’m hearing way more sounds from my familiar music material, I struggled to pull myself away last night listening for hours. The soundstage is more defined and hearing the smallest sounds easily as if in the clear. Very important to me I’m getting the best emotional connection to my music.
@ ANONYMOUS You suggest Encapsulated 15VA to 500VA : The Talema Group though this is a completely different transformer not fully custom, see above reply to oddeophile - 10.8 secondary
We all have a different approach I’ve been on this journey since the PWD mk1 and happy to support PS Audio with A Mk11 DS if it sounds superior to my modded MK1 DS in a side by side comparison. The MK11 DS has a lot of competition, the recent mods Edcor and PSU Audio board are huge, the DS MK1 DAC sounds way more powerful as if a mini car was bumped out of the way by Kenworth rolling through. That’s the sense/feeling I get after these upgrades. I look forward to the MK11 DSD DAC
Cheers

The daughter card on the Bridge II is indeed the worst offender (by far.)
The AC inlet doesn’t radiate any more than the AC wires in the box. The main PSU radiates some 60 and 120Hz, but it’s the high frequencies that the ERS is designed to attenuate.
Yes, thanks, so I guess shielding the lower frequencies of a PSU means distance and enclosure.
Very nice excellent
Don’t worry, if we score it out of 10 difficulty levels, the difficulty of making mods is 3.
Good soldering skills solve everything.
All good ANONYMOUS, agree absolutely Ted would produce a MK11 DAC superior than the existing MK1. Though the modded MK1 is significant levels superior in SQ to the standard MK1. I would want to hear the modded MK1 in a side by side comparison with he Mk11
All the best John
bridge ii, rejected son for psaudio?
Just to let you know that I ordered the XS4400 from Edcor directly and got the replacement done at Audiophonie in Montreal. It took about 1hour (less than $100 CAD) for the technician to do the work. Ask for Arnaud. He did a great job!
For the external Lpsu, I will do it myself.
Everything anyone has said( who have done the mod) about the XS4400 from Edcor is spot on. I just finished installing the board and am listening as I type. Awesome. I also have a new PP3 in the mix , but having read what people have experienced with the PP3 and or the Edcor mod, I can sort of hear what each is bringing to the mix. And if I am wrong as to which is doing which, don’t care, it sounds amazing, a very happy camper indeed.
A heads up, if anybody in the GTA is looking for a place to have the mod done, May I recommend Audio Excellence, very top notch workmanship. Ask for Vilip,
Thank you very much @elessard for the tip.
Initially, I was very very skeptical about your suggestion to go to Audiophonie as I bought a Unison Research Unico Nuovo integrated amplifier a few years ago at this store and I had also bought the phono card. However, when I came to pick up the amplifier, one of the previous owner greeted me, pull my brand new Unico Nuovo out of the box, put it on the side over an extremely dirty piece of shag carpet littered with resistors, cut wires and all kind of junk: I was screaming inside of myself telling me he is going to scratch my brand new amplifier, which he did 
…
Anyway, there was no way I was going back to these owners.
But, after I called, I found out it is an entirely new owner with 5 technicians working full time and their working bench is perfect 
: - so thank you very much for the tip : I will certainly ask for Arnaud.
How much did you pay for transformers replacement ?
My Xs 4400 are on the way … I ordered them the 14th they shipped today
Looking forward to some new sounds, I’ll have to wait till fall as I’m voicing new speakers now and need to compare my old to new with known sound
I believe all audio/audiophile observations are relative.
Furthermore, I understood Ted’ s referenced comment to be a “comparative comment” - as to its relative contribution of noise.
Don’t mean to speak for Ted here, though…
IME, the Bridge II Ethernet card is an excellent performer.
FWIW.
i think bridge ii has been treated unfairly
I think it was 24.95 US each. I ordered from Edcor direct.
How much installation ?
Thx John!! So thankful brother.
Richard
And I just had Dan Santoni, tech extraordinaire in Hamilton, Ontario retrofit the Edcor transformers to my DSD. $120 CAD for the work just like @dts experienced. $700 is robbery.
