Ref. Wattgate plugs: I own the Cabledyne cords and they are excellent for the money around $160. I did try these cords with the Furutech FI-50 series plugs and the sound improved greatly (with the addition of better outlets) but at far more dollars. With the upgraded plugs, it brought the price up to $660 but now the cord easily compares to cords in the 4-figure price range.
In summary plugs do matter.
