I disagree with the basic idea that studio monitors are not appropriate for home use. There are several well known audiophiles who use speakers that are considered "monitors" and there are countless studios that use speakers that are considered home audiophile speakers. As with everything in audio, it's a matter of personal taste. Recording engineers are just as diverse as audiophile listeners. The classification of speakers as "studio monitors" is really more of a marketing tactic to focus sales on a particular market.
As one upgrades their system the typical result is that it gets more resolving. It is entirely possible that at some point the extreme detail might become distracting or unpleasant. I heard a pair of big Wilsons with D' Agostino amplification at AXPONA a few years ago and I didn't like the sound. I would describe it as "etched" and it was like blowing up a beautiful digital picture until you could see each pixel. Some people I talked to felt like I did but others thought that room had the best sound at the show. This really showed me that it is a matter of taste.
So, if your asking whether or not you can upgrade your system to the point where it becomes too detailed and resolving my answer would be yes, depending on your personal taste.
