For the technically inquisitive folks, the file below shows some graphs comparing the performance difference between the old efx loop and the new one.
The graphs show the frequency response of the loops without cables attached and the frequency response with 50ft of standard guitar cable (30pF per foot capacitance) and the effects of the high frequency response. There are also graphs showing noise analysis comparisons.
