Both are balanced cables - only the connector is different. Both cables will sound the same.
I beleive the Vci-400 has “unbalanced” TS out and balanced XLR outs. There is no "R"ing and therefore the line is not balanced but TRS cables will work just fine. The balanced XLR outs will allow for less interference with long cable runs and reduce the chance of a ground loop issue when connecting to a poorly setup/grounded sound system. You will not have these issues when connecting to your krks. Use the XLR out when gigging and either at home.
