I'm reviving this long-asleep thread because I've been wondering about the same thing, and the descriptions here (apart from Bojack's) are the opposite of the description and measurements in the Stereophile review of both speakers. Stereophile ain't my bible, but I'd been leaning toward the "se" because they'd described and measured it as the more laid back--and in my small room that's what I'm going for. Listening before buying seems unlikely for me, especially as both models have apparently been supplanted by the 3/5r. Of the three (plain, se, and r) I'll probably go with the plain or se to fit my price range used, whichever is the more reserved in the treble. Any input would be valuable. Thanks!
