I'm on my phone so can't check a few things. The Tomanek site should/did have an English version.
The do here
http://tomanek.net.pl/tomanek-liniowy-z ... wieku.html an Auralic LPSU For 800 Zloty (about 160 GBP)
Tomanek specialise in making high-quality transformers for audiophile use and the unit I have works perfectly.
You can email them for more info.

Its not hard to make a good linear power supply. Once again because it has become *a market* the complications and the bullshit associated with them is appearing. FFS a linear power supply is a transformer (more VA the better) a rectifier circuit, a simple high current bridge is more than adequate, and some capacitance (different arguments for how much) and maybe some bypasses. IT IS THAT SIMPLE it is not rocket science.
EDIT - and the option of a regulator circuit, which is a simple unity gain amplifier, simplest form LM317 and if split rail plus LM337, though you can complicate this if you want until the cows come home.

Actually I did enquire - and their mini version of their higher end PSU looks good enough (perhaps you can double check for me) - this was their response...
ULPS mini for Auralic Aries Mini 15VDC 1A: 400 PLN
Shipping to UK: 100 PLN
Total: 500 PLN

If you want to make your own linear power supply then you could use a LT1083 module from Ebay as the rectifier and regulator.
I've used this one on several projects, cheap enough but have to wait some weeks for delivery.
