I have the R3000 and have been getting some excellent results from it. I have a few questions/comments for you:
1. Are you soft proofing using the correct paper profile?
2. Are you setting the rendering intent the same for soft proofing and for printing?
3. Ensure ICM is turned OFF in the printer profile and use PS (I use LR) manages colors
4. Set the highest quality in the printer driver
5. Set the correct paper type in the printer driver
6. Set the correct paper for output from LR or PS
7. Use the out of gamut warning in PS (or LR) and correct the out of gamut areas before you print (typically by desaturating the areas flagged as out of gamut).
8. Using LR and my NEC PA series monitor calibrated to a contrast ratio of ~300:1 I get a spot on match when Simulate Paper and Ink is UNCHECKED. Go figure ... I'm used to doing the opposite with my Dell eIPS monitor when using EZPrints (one of Smugmug's labs). This could be a bit monitor/calibration specific, so experiment to see what works best for your setup.
9. What is the lighting like where you are viewing the prints? If your system is set up to have great looking prints hung up in a nice brightly lit room but your viewing the printed output under dim tungsten lighting you could be trying to fix a problem that doesn't exist. 
Also, when I calibrate my monitor I make sure it's been on for over 1/2 hour before starting my first calibration run then I calibrate about 4-5 times in a row. Again for my NEC (with NEC's calibration system), my delta E seems to improve a bit with each successive calibration. I haven't bother to check to see if the accuracy improvement is just because the puck warms up against the screen or if the new "starting point" helps the software hone in on the optimum result.
I will say that getting matte prints from the R3000 to match what I see on my monitor has been more challenging than for luster or glossy. I think that part of the issue is that I need to have a monitor calibration with a contrast ratio closer to 200:1 that I can switch to prior to soft proofing with a matte paper profile. Matte will also have a lot more out of gamut colors to correct and reflects light differently, so I shouldn't expect the final result to match what I'd see with a glossy or luster print anyway.
