Unable to audition used speakers a problem

Thanks to all. All good points. This gives me a different perspective and is very helpful. Space issues, spouse issues, tire kickers, etc. I agree.

Timrhu: Good question.
Prefer to buy locally as floor-standing speakers are the most susceptible to damage in shipping (size, weight) and can be more difficult to repair if damaged in shipping (assumption), especially if: manufacturer is out of business; or custom drivers; or cabinet is damaged (badly dented speaker cabinet not as easy to repair and likely effects performance more than a badly dented amp, assuming electronics are not badly damaged). I worry more about shipping speakers than other gear.
Prefer to audition because IMO speakers are more difficult to evaluate than other gear when they have not been heard. IMO, if electronic gear is scientifically sound, well built, and proven over time, then I have far more confidence that it will sound as I suspect and can therefore be purchased unheard. IMO speakers are infinitely more subjective regardless of their build and specifications. I have pursued used speakers I had never before heard, but only after a lot of investigation and only ones which meet my requirements. I'd rather hear them before I purchase. Hmm ... (self evaluating here) does that make me a tire kicker? After all, if they sound at all like they are purported or I suspect, then I'd buy them. So I don't think so.
So, personal situation and preference dictates much easier to bring into my home different electronics rather than speakers.
But I had not thought of requesting a three-day trial period. I think that is a very good idea. It would better prove to the seller that I was acting in good faith and not just a "tire kicker". Especially if they are holding my money. And if the speakers perform up to (agreed upon) par, then they're mine.

Ozzy62,

You strike me as someone who puts little credence in the importance of front end equipment.

Incorrectly struck. Perhaps I was not clear in expressing that the front-end equipment, if properly engineered and built (such as my relatively inexpensive front-end: used Opera Audio Consonance Reference 2.2 CDP; Mapletree 2A SE pre; Van Alstine Ultra 550 Fet Valve amp), would likely not sound much differently TO ME than other similar gear built and engineered equally as well, compared to speakers. I assume (based on my experiences thus far, though I admittedly have not heard a great amount of equipment/speakers) that I would be more sensitive (liking/disliking) to different speakers than I would different front-ends. Should I never audition speakers anywhere else except for my room and with my own gear if allowed the opportunity? Of course not. I realize all of the variables involved. For example, one thing I would do to minimize variability would be to audition speakers at such a volume where room modes would not effect the sound. And as far as the front-end gear is concerned, I've offered to do what you've suggested - bring in some of my front-end gear. That way even the seller has an opportunity to hear different gear as well - perhaps a good time will be had by all.
