..what I really start to like in Reaper is its routingstuff. One of the things I'm going to do when time permits me is using the Mastersends to setup an active monitorsystem, all filtering done on Reaper's masterchannel. One of the biggies in monitoring is to avoid bassloudspeakers that compress the sound. Most homesystems do that, one can make serious mistakes mixing on those. They also tend to add some serious distortion in the LF region. Better get oversized monitors than handy little ones, or a good servosub. The bigger the bassloudspeaker, the lower it's resonantfrequency. Around that frequency serious delays in LFreproduction pop up, along with horrible impulseresponse. Check your mixes of different systems, that's the key. And get a good pair of cans, with a Chinese class-a headphoneamp (with an spdif-input). Since I use Sennheiser's HD-25 on such an outboard headphoneamp my mixes have improved a lot.
