My story is very similar to stereo5. I have not heard the other two choices, but the Rogue RP5 was my main preamplifier for a couple of years. I have gone from all Rogue to all Mcintosh in that system. I am not sure that it is any better, but it is different. Originally I had the RP 5 feeding the Atlas Magnum KT 120 tube amplifier. I transitioned to the RP 7/Stereo 100 combination. Then to my current McIntosh C 2300/275 Mk VI System. Sonically, the RP 5/atlas magnum gave me everything that I needed. I liked it better than the RP 7/Stereo 100 combination. I found it to be more dynamic and full sounding than the more expensive Rogue pairing. I also used the RP 5 with several other amplifiers during the time that I had it and thought it was a very good preamplifier!
