I am upgrading from RM6900 and trying to pick between a set of used RTi8 vs brand new Monitor 60. They cost exactly same. From reading posts here, RTi seems to be everyone's favorite but I am splitting hair since Monitor 60 has rave reviews as well on internet and they are new. They will be used for a mix of movies and music. I hate to torture myself again in few years with this selection process when there is no right answer (more like the personality test - its not possible to fail it and results are moderately diagnostic at best) and stores don't carry two side by side in Canada. Thanks in advance for the input.
