For my preamp I used a DEQX HDP-5, which as you may be aware is produced by some of your fellow countrymen Down Under, and provides numerous DSP-based functions including improving speaker time coherence and room correction. To make that possible analog inputs are converted to digital
Yes I know Kim and Al very well, they are 200mts down the road from me in Brookvale.
So Al now I know it's not possible for you to go passive with the Herron, as you use the Deqx as the pre, your converting your vinyl to digital then doing room/speaker digital eq'ing and xover'ing to it, then bringing it back to analogue domain again.
