What speaker could safely be ordered without hearing it first?

None of them. 

None of them. 

I live in a state that is more or less an audio store desert unless you count Best Buy. I’m in the similar situation you find yourself in, in that, how do I go about buying or demo’ing speakers for my system. This means I’m trying out the limited line of speakers offered by larger on-line retailers like Crutchfield or Audio Advice. Both of which I’ve purchased recent component upgrades from and been very happy with. I’ve also found a few direct-to-consumer speaker companies that I may demo for my system. My short list of options is based on my listening criteria of moderate listening volume in a largish room. Limited to stand mount speakers due to Wife Acceptance Factor.

Narrowing down to the following:

Aperion Verus V8B

Martin Logan Motion XT B100

MoFi Source Point 8

Sonus Faber Sonetto II

KEF R3 Meta

JBL L82

When I"m able to build my listening room / library in a few years I'm getting the Vandersteen 2CE Sig 3 floor standers. 

MBL 101e mk2 would be my best guess at a speaker most liked and least disliked if heard based on many very positive reviews and live demos at audio shows.  Requires ample amplification.  

I don’t trust anybody else’s ears. They’re not attached to my head, and regardless of what any reviewer says in even the most comprehensive of reviews, that guy doesn’t know my room, my tastes, or my experience, and I’ve returned one too many speakers. My favorite speakers I've owned over the years have all been auditioned, and could have been returned. Here’s a recent thing: I was considering a pair of well regarded Volti Audio Razz speakers since I like horns, and they state on their site, "Volti Audio does not accept returns of product for any reason." That’s a direct lift from their site. Make a deposit and they keep the money...period. OK...Volti Audio will not be getting any of my money for any reason (maybe if they kidnap my grandson I’ll have to make an exception, but that seems unlikely). The designer/owner claims they get very little criticism and extremely few issues with their precious speakers, and warranty their speakers for AN ENTIRE YEAR. Yeah man...he also claims he’s there for his customers if issues arise. All true perhaps, but nope...no Razz for me!
