Yes I understand your concerns which are all very valid, but changing speakers is always a challenge and more so if a home demonstration is not possible.
But, nothing venture nothing gain.
Audio shows have their limitations in assessing different speakers for all sorts of well known reasons. Finding ones that have the right synergy with your existing system is also a key consideration.
I am on my third pair of YG speakers, namely Hailey Reference 2.2 , which I consider to be outstanding but well above your price range. A used pair of Carmels could be an option if you like their sound.
I was attracted to YG by a review of the Carmel 1s a long time ago and I paid my first visit to Munich specifically to hear them. The room YG had for that show was excellent and their sound confirmed what I had read.
In my experience audio components all have distinct characteristics to their sound and all my three pairs of YGs have reproduced and brought out their differences and nuances because of their inherent and first class neutrality.
Going to one of the shows mentioned should give you an opportunity to assess different options and find some that appeal to you. Careful reading of review, ie reading between the lines, can often provide the additional insights to supplement your show listening experiences.
In my experience it is a journey worth making as long as you do your homework and take your time. It is one that can bring significant rewards
