ALL PSU’S COME FITTED WITH AN OYAIDE GOLD PLATED DC PLUG AS STANDARD UNLESS OTHEWISE ADVISED

Mains Cables R Us and Longdog Audio offer a linear power supply selector for customers whose DAC or streaming device is not listed in our standard webshop. As new DAC’s are being introduced weekly the list is enormous. We have complied a list below of all the known DAC’s which are powered by SMPS wall wart plugs (DC) which do nothing for sound quality whatsoever.

Changing to one of our linear power supplies will bring immediate sonic improvements, proven by our own listening tests and the 100’s of satisfied customers who now use our PSU’s.

Please do not confuse these products with similar mass market equivalents, ours are hand built in the UK and offer various tweaks and up-grades which are not offered by comepting products, some do not even supply a mains lead with the PSU. The design for ours uses 2 seperate cases with the smaller case sitting next to the item it is powering and the larger case being sited away, this gives the best possible performance and it works.
