Those of you who own 5A's.... I tried switching out the original power cords with home made ones....Oyeida plug and Accrolink wire.... I know that Richard says there is no difference, but to these ears and in my system it was a WOW. Not only did the bass change to cleaner and clearer, but so too did the mids the highs, and everything in between. Be wary though that you cannot use Oyeida or similar high end plug for the Vandersteen amp side, since the fins of the amp wont let the plug be fully inserted. Also....make absolutely sure you use the ground - serious damage to the amp will result if it is not grounded (3rd pin).
