As I'm in the process of putting my rig back to gether again just this week,I've coupled two sets of no name RCA ICs using only one side from my Onkyo Receiver...
In the past I've run via this same cable (s) from both my Bel Canto DAC3 and Thor preamp. On the Thor I had to use a pair of "Y's", as it has only one set of active RCA outputs.
I've detected no adverse issues in the sub's sonics in any of the above configs.
I will be spending more time this go 'round in placement, and will ultimately go with one run of RCA cables to the sub... personally, I like the idea of using a preamps outputs, rather than an added set of speaker cables.
