I'm looking for a pair of interconnects that won't shatter the bank....

Hi stereoisomer,. 
Yes, the minefield of wire is daunting.  I won't bore you and Members with qualifications...past posts cover some.  I recently upgraded interconnects both to my main monitors as well as to my 2 subwoofers with Luminous Audio cables. 
I have reached a place in my process of refinement where the upgrades don't attempt to fix or correct anything that seems missing or off, rather,  it's a reach for more reality from the illusion.  Instead of attending the musical event, by bringing the event into YOUR space.
The Synchestra Reference now pair to the mains and the Monarch II's to the 2 subwoofers.  To the subs, I was running some nicely made Mogami.  And yes, the upgrade to the subs is significant, contrary to the opinions above. Tonality, apparent speed and depth is substantially improved.  The Synchestras reach into the worlds of the exotics at a fraction of the cost, which is Tim Stinson's niche.  His twenty years of design and impassioned listening result in a soundstage and dimensionality  for purists.  Onwards, and More Peace..Pin

Luminous Monarch II's are $119.00 for a 1 meter run.  Do yourselves a favor...and ya, subs benefit.  MP, Pin

Hi big_greg,

Depending, yep, exotic wire to subwoofers in a good hi-fi system may not be the greatest value.   That said, when fine tuning a highly resolving system where thoughtful, meticulous choices have been made over years of improvements, everything matters. 
My two sealed (non-ported) revealing subwoofers retail for about $2,200.00, the pair.   Upgrading from my basic Mogami cable (well under $50.00) to Luminous Audio Technology's entry level interconnects ($119.00 one meter) proved wonderfully effective.  Deep, tuneful low bass is a construct for improving the rest of the frequencies. 
These choices are led by degree of passion in one's pursuits.  Money well spent here.  More Peace.  Pin
