Like Hochopeper says, I'd personally go with a higher VA rating. Personally use a 15VA unit to power the JG Buffer section on a couple of Curryman DACs with 'The Wire' PSU v.1... no problems so far, and should be OK powering up to four units once I'm ready to go with a 4-way amp/speaker build
Stay away from that transformer that's the one I use and it was very cheaply made the wires were very thin and only single insulated and it died on me within a week. I replaced it with an Antek for half the price and it is much better made with double insulated wires on both the primary and secondaries.
What enclosures are most of you using for your Wire builds? I made a mistake and ordered and enclosure that is to shallow to fit the power supply boards without having to redo them with shorter capacitors and heat sinks 
If anyone has any reasonably priced options please let me know I'd really like to give the amp a nicer enclosure then the plastic Radio Shack box it's in right now.

Take a look at what this gentleman on eBay has for sale...

You can have him make you a custom case for around the same price. It isn't the cheapest option, but I think it's one of the better options....

They look very nice, but might be better suited to tube amps. Implementing a volume control might be a little more of a challenge.
I crammed mine into a 6" Box Enclosures BEX 4 chassis. If you want a little more room, opt for the 8". A fellow DIYer (john) here in Ottawa helped me cut out the front and back panels from Sipo wood on the laser cutter at a local art/tech co-op. The picture is of one of my amplifiers, but you get the idea
Overall cost was less than $50.
Cheers,
Owen

Thanks those look very nice but they are a bit more then I'd like to spend on this project.
That looks really nice! I'm familiar with Box Enclosures from my O2 build but I was afraid it would be difficult to get everything mounted without a removable top cover. Did you have any trouble with that? BTW Ive been listening to my SE-SE for about two weeks now and I've never heard my HD580s sound so good!Try here:

This is mine from Hammond, available on Mouser and RS (I do not know why, but the picture when uploaded is rotated).

That came out really nice do you happen to know the Hammond part#? Did you have to mount your power supply board on its side or did it fit standing up?
The Hammond product number is 1455Q1601. In the attached picture you can see how I mounted the pcbs. I could put the PSU standing up but I needed to use very short standoffs. The dept of the enclosure is only 160mm; as you can see in the picture the trafo is very near the amp board: no noise at all when it sounds, but now I would prefer the only deeper enclosure (n. 1555Q2201, 220mm deep). I like its Apple Mac look.

Yeah the chassis made by 01robo on eBay are well worth the mula. They may be marketed towards those building tube amps, though I've used a few on amps and a DAC and just flipped the case and things came out fine. I know Misterrogers uses these chassis as well and he builds his with the chassis in its default orientation. BTW, you can have him make the chassis any dimensions you want.
Thanks that looks perfect
. I think I may go with the next size larger because I planning to add an onboard USB DAC in the future. The one you used looks to be about the same size as my temporary plastic enclosure. It's a little bit cramped but even with the messy wiring it's dead silent even on sensitive IEMs! The Wire really is an amazing little ampAn externally hosted image should be here but it was not working when we last tested it.

Hi,
can you tell me how did you wire the pcbs to the enclosure ground?
Did you connect the PSU input AC OV to the chassis ground?
Thank you
northernsky
All I did was connect a wire from the power supply pcb ground to the chassis ground. I'm not sure if it's the best/right way I just did the wiring the fast and easy way since it was only temporary. Here's a pic showing where I connected the wire from the chassis ground.
Thanks again for the Hammond enclosure recommendation. I'm going to order this one from Mouserhammond 1455q2201.
I went with a slightly bigger size so I could keep my wiring nice and neat and also have enough room to add an onboard DAC in the future.

Thank you for your detailed reply; you confirmed my toughts, I did the same.
