Just a thought, but have you considered a road trip? Here and there over the decades I've been in this hobby I've taken a trip to hear speakers that I've been considering. It's paid off both ways -- finding a prize and avoiding a mistake.
The only criticism of this approach is that you don't get to hear them with your room's acoustics, but I've always been able to pick up the fundamental character of the speakers.
Of course, it depends on where you live and where you have to go to hear the speakers -- a couple hundred mile round trip in a car is one thing while adding air fare, car rental and hotels adds a whole 'nother cost factor.
As noted, just throwing it out there.
