It would probably be cheaper to swap amps John! Then the enclosure would probably be massive, although it does make you wonder if its possible? lt dosent bother me to that extent,the main thing, they're a great sounding amp. Hopefully it will give a small gain You lost me? Special in what way Mike? Me ? Few go as far as we do to extract more music out of our kit

Think about the switching frequenices within the power supply and how the interact with the amplifier and conducted emissions, with care measuring for exact sizes you could fabicate an ally can to enlose as much of the chopper section as possible, or even better the whole of ther psu. BUT be careful to make sure NOTHING touches the psu board, better still put them in a better case with more space to work and one where can use the G2 with gay abandonement. Its a fiddle but it will help Doing the 2nd Monoblock got me thinking tonight, l could fit a divider straight down the middle of the case and sheilded it, The PSU is a tricky one,due to heat,..Possibly a wire mesh with small holes? That will allow me too sheild the other section,that l don't believe is so heat dependent? Hopefully Tony you can confirm this?

lt's been quiet on the listening front, although l have been keeping grey matter busy. So l took a pause on the Nord 1ET400A Monoblocks, while l digested Tony's suggestions. I admit at this point,l contacted Colin from Nord Acoustics and inquired with him if he sells 2 longer leads,Power and Ribbon cable,in view of separating the power supply. Colin said in would sound worse,"Would be of NO benefit and performance would actually be worse" when l ask why he replied "Losses over long cables danger etc. The SMPS have almost zero radiation. You get more from the cable itself., Example Each individual power transistor is wrapped in copper foil". Interesting and thankfully l had sheilded the cables already. This lead me to abandon the two box approach,and focus on a box within a box method... Nord 1ET400A Sheilded by Damien Read, on Flickr So if you take glance from my last photos, l have introduced a 1.2mm piece of solid copper,and made small holes for the power and ribbon cables to pass through. At the bottom of the case there is a,air vent, this has been covered up with fine copper mesh. Nord 1ET400A Airflow check by Damien Read, on Flickr I thought l would show this photo as an example of the copper mesh, it allows light and air flow whilst it's sheilding. Nord 1ET400A Sheilded Finished by Damien Read, on Flickr The finished item,if you look closely, l covered the inside of the case on the upper air vents,this also sits on top of the copper divider that separates both components. l don't know of any Hypex unit on the market that has gone to the lengths,it seems manufacturers just place them in the enclosure together, fingers crossed it will be worth the hassle...Roll on having power!

Nice job, how does it compare before and after the mods?

I would go carefully with the upgrades it might be a problem to find out what is causing a issue if a backwards step

It is exacatly the same but with a more refined op amp input stage.

There all based around the same design Martin, it's just that Nord offer Op amps sections.l ran the standard one, and it was okay,a bit sterile. Adding the Sonic Image Ops made a big difference in my view. It's all subjective at the end of day,but the opp amps offered more texture, width.

Well you know I can't sit still.....And one positive thing of not having power to listen to my Hi-FI is the amount of HI -FI projects I've finish. A minor update, but a very positive, and hopefully permanant solution. As you may recall, I have been banging on about how I love the Sound Quality of Volumio 3, but loath it's laggy behaviour,l would been looking for files in folders....Honestly 6 to 8 Seconds to open a folder, before you could play a song! So I have been on the search for a Linux Based OS Music Program, and thats half the battle, trying to research the good the bad and the ugly. Today I installed Daphile on my old NUC N4000. I have to say,and credit where it's due, Dalphile runs really smooth, instance access to your folders, all album covers displayed straight off the bat,and even the abilty to use a Windows PC and copy and paste your files to the drive. Dalphile has lots of bells and whistles,and it looks like the designer of the software has been slowly refining his software,instead of abandonment Of course it should do this, but experience begs to differ. Anyone intersted can take a look at his site www.daphile.com/Thats great news for myself, with one final test....Can it match Volomio 3 in sound quality....I really hope so

Today I installed Daphile on my old NUC N4000. What does it run on, Damien? Linux? Or is it self-contained?

From the site Martin..Daaphile is based on the open source Squeezebox Server, Squeezelite and Linux. Since Daphile is used and configured completely via the web interface the user is not required to have any Linux skills.
Hope that helps

I hope you get your power back on soon Damien as I’m eager to hear how all your mods turned out.

That’s the spirit 😃 I opened up my dsp earlier and applied the Graphene to its Dc fuse. Another nice increase in sound quality.
