I have a pair of the slightly hot-rodded xls encores, so I know what you're presently hearing.
I also have a couple different pairs of pro monitors that are quite a bit better than the xls. (By "better" I mean they are uncannily devoid of audible tells or coloration, leaving the music revealed in all its glory. Crazy good imaging, the proverbial speaker disappearing act, just the music.) So if looks/WAF arent a concern and you want to get max value, maybe consider pro audio options. $2K would get you into the realm of serious, no compromise monitors.
I'll also second the BMR rec. They too are remarkably natural, neutral, devoid of audible tells, and truly excellent speakers.
