I'm looking for a bi-wirable integrated amp or pre/power combo

Just to note that any amp can be used with biwiring cables - you don't need two sets of speaker outputs for each channel. Sorry if the stuff below is teaching Granny to suck eggs, iRog, but it may be of some use to other readers...
Most amps have combination terminals like this
for the speakers, so you could use spade connectors like those below left for the bass cables, and banana plugs like those below right for the treble, both into the same speaker connector at the same time. The spade goes into the slot, and the collar screws down to clamp it, while the banana plug pushes into the hole on the end as usual.

If you don't want to do this, or happen to have an amp that will only take banana plugs, you can get your biwire cables made up in 2-to-4 configuration, where two conductors are fitted into each plug at the amp end, but there are four - two positive and two negative - at the speaker end, as seen below.
