In response to which wire to utilize and bi-wiring options on the VR-4jr:
The best sonics will come from either bi-wiring or single wiring to the M/T cabinet then jumping down to the bass module.
This eliminates the extra connections when using the data-link cable and eliminates the jumper bar. These are very revealing speakers, those extra connections are audible even if the data-link and the jumper bars were the best cable available.
If you are already utilizing some very reavealing wire, the jumper bar and data-link will inhibit performance.
Now there is also a tonal balance difference between bi-wiring and jumping the cabinets. Bi-wiring may make the bass cabinet seem louder leaving you with a warmer sound.

These speakers are smoooooth. If you hear what you may describe as grain, it's extra connections using the jumper-bar and data-link. And always connect to the M/T first.
