I haven't tried the ref1000, I just have read about the smaller wattage brothers and listened to those. FYI on the Rowland it takes like 800hrs for those to break in, but still not the level of refinement I think you are looking for.
Yes the brass jumpers are considered inferior for the most part on my NHT 3.3's I used some Silver Streak jumpers before buying the transparent jumpers.. The NHT's didn't improve with the jumper configuration, because of their crossover design. I found that connecting to the tweater section top half and then jumpering down to the woofer binding posts did improve on true biwire cable. You will see a bunch of used jumpers.. I think it only cost me less than $300 on the transparent reference jumpers.. if you buy used they sell for under $150. Other brands sell for cheap. I still need to post my silver streak jumpers up on agon..
