Hello Nuforce or anybody in the know, please advise if the above is even possible.  I prefer speaker out to sub for better transaparency and impact but heard that it cannot be done with Nuforce digital amps.  I think there was a workaround solution but cannot find it.  I am currently using MCH3SE-C7.

Please advise and thanks,

Kenobi

Switching amp such as Nuforce and some others have half rail DC offset versus ground.  Many sub woofers are capable of accepting such input but you must check with the manufacturer.
For example:
Martin Logan speakers after 2006 (please check as I am not certain of this date) will work just fine and you can get an upgrade.
REL, through their US distributor, provides an adapter for connecting from speaker terminal to the sub input.
