I hope you have an opportunity to go to stores, shows, other homes (is there an audiophile club in your area?) to hear a broad range of speakers. The fact is that not everyone wants the same things from their sound system. When I first started in this hobby/lifestyle, I had a friend that was a drummer. After listening to every speaker he could find in the area, he bought his dream speakers and they are truly legendary - the Rogers LS3/5A. They're still in production ~50 years later. They're also tiny standmounts, use a 4.5" woofer, and feature a well-designed bass "hump" to get semi-decent low frequency extension. However, what he wanted most was speakers that imaged properly and I have yet to hear speakers that I would swear better the LS3/5A in that aspect.
Most speaker makers will sell 1 or more standmount and tower type speakers. Many of the larger, more established brands will have more than 1 line - reference and standard, maybe even home theater or wall-mount variations. For example, KEF has Q ("affordable Hi-Fi"), R ("performance redefined"), Reference ("detail remastered") lines, plus more. The LS50 is not part of any line, as it's too refined for Q, and lacks the bass performance required of an R. While you might not end up preferring the KEF sound, hearing comparable speakers from the Q and R ranges (or any other maker with a similar model profile) might help you decide how far up-market you need to go to be satisfied.
