Musician vs. audiophile

In general, Wilson speakers sound great when... they are properly matched to other components, proper cabling, and pretty good to great acoustics (and positioning) in the room.  If they sound flat and uninteresting it is not unusual at all.  However, this is the 3rd iteration of Sophia's and they should (normally) be the cornerstone of your system.  A Wilson dealer should come over and see and hear your system and make some suggestions starting with the most cost-effective ones 1st.  If you can afford a more forgiving pair of speakers there are several i can think of, but that could involve a lot
of money, time, and effort as well.  I always wanted the accuracy of Wilson's but i thought i could do better elsewhere and for less money and ended up with a giant-killing pair of Eggleston Andra's.
Anything similar to those would IMO add a great measure of musicality to most normal living rooms (Merlins, Sonus Faber, Reference 3a's, Focal, etc.).  

This is all wonderfully academic for sure, but i have heard Wilson speakers sound sublime and quite wonderful at times, and dreadful
at other times, depending more on EXTERNAL FACTORS than an internal flaw in the speakers themselves.  As for musicians having a different sense of what sounds more like the real thing or not, I cannot agree less.  If they just don't care due to their stubborness and/or narrow point of view, that's separate from knowing good and well what sounds natural and what doesn't.  The 1st time i heard a good pair of acoustic suspension speakers back at the ripe old age of 9 or 10, i knew that i was hearing bass that went deeper, far less harmonic distortion, and highs that were more open and airy.  Was it Majico good or B&W good?  We can argue over THAT, but let's not kid ourselves over the basics.  The poster & wife simply have issues with the end results they are getting when they sit down to listen to music, and a trustworthy audio shop (or a capable friend) could help them out to get better sound regardless.  And furthermore, they have speakers that cost an arm and a leg to start with, along with other esoteric components.
