Quad 57s with after market power cords

Changing power cords is very efficacious for my Kingsound King III ESL speakers (reviewed for Dagogo.com), and in fact I tune the system partly by using different power cords with the ESL speakers' power supplies. 

I had several people insist it would not change with power cord. I invited one repairer of Quads to come; he heard and admitted he was wrong. 

Good point regarding outlets, maplegrovemusic. 

Amen on the sans grills! One of the worst moves in listening, imo, is to shove a screen ahead of a driver. :(
