Yup exactly - a saving grace that it is a fairly cheap experiment. I hope he gets over the connection type eventually and focuses more on the end result. I also really want to send him the pain Love4Sound went thru integrating his subs, but a bit scared about showing him this forums way - just in case he eventually gets to this post (if he hasn't already)
.
Regardless - I have requested him to try both RCA (his way) and a single sub out from his node 2i to see the real difference with the connections at each location and go with what he prefers, regardless of what 'the Paul' says.
