Mesch, my Mains Cables R Us unit (specifically designed for the Chord QuteHD dac) was $500 including shipping from the UK to US. I upgraded a few things such as fuses and silver cabling......the basic unit is a bit over 3 hundred US dollars or so, but that excludes any required shipping expenses. Here is the web site if you wish to check it out:
