IMHO, That is a good sub, but not the greatest. Personally, if hampered with budget constaints, I would wait, and later spend a little more, and get a sub that gets down into the mid-high 20Hz range. You'll "feel" the difference.
Either is a good match for the Monitor 50 Front L/R speakers.

Correct, Important, but not as important as the Front three speakers.
Some quick searches revealed that the Yamaha did not get very good expert reviews. It is actually the same receiver sold with the Yamaha product number: HTR-6230, as a HTIB (Home theater in a Box, Receiver/speakers combo). Apparantly it has problems with providing sound from a Blu-Ray player. Sound can not be passed through the HDMI, and apparantly even using a digital "Audio" connection, (Optical or Coax), in conjunction with HDMI for Video, dosen't solve the problem. There is also a whole bunch of conflicting information on Yamaha's rated output. Not to be unexpected, but it appears that the (typcially inflated, as I mentioned before), rated 100 w/channel is actually @6-Ohms, which means at 8-Ohms is something less. Also, (and this is not typical for Yamaha), Reviews stated that this particular receiver lacks "clarity" in reproducing voices in movie soundtracks.
The Pioneer on the other hand has gotten some steller reviews, given its budget price tag.
And I'm glad I caught your Edit.. One expert reviewer made the comment that the only other comparable receiver to the Pioneer able to handle LPCM decoded from a blu-ray player, in this price range is the Sony STR-DH700, but went on to pan the Sony, for having "sub-par" sound, and no onscreen display.
