Asahitoro, many of those who have posted above have tried to offer helpful suggestions based largely on experiences with their own systems. Some have also advocated one way or the other based on what I would classify as generalities, the applicability of which is doubtful given the pretty much unique nature of your speakers. Each speaker containing two drivers and two different class D power amplifiers, with an A/D converter, a D/A converter, numerous digital interfaces, an analog interface, sophisticated digital signal processing, and preamp functionality also being incorporated. Not to mention that AC line voltage and noise conditions vary considerably among different locations.
So with due respect to the others, I would not assume that what has been said has much if any applicability to these particular speakers, at your particular location and in your particular setup. What I would suggest that you do, if you already haven’t, is some Googling to see if anyone has reported trying upgraded power cords with the wireless LS50. And beyond that, as some have suggested just try a pair of cords, or perhaps two pairs, that you can either return or sell with minimal or no loss if they don’t help.
Good luck. Regards,
