Sonic_genius, could it be that all those you tested really are roughly equivalent, and the Nextgen jacks would have improved them all about equally?
rca plugs - comparisons?
anyone test or compare rca plugs on identical cables, noticed diffences or improvements? top wbt and eichman rca's have "new and improved" designs, are they better, or just different? is it worth the expense to change/upgrade the plugs on a decent older cable or specify the expensive wbt's, where it is optional?
