What speaker could safely be ordered without hearing it first?

@OP, we (Dutch & Dutch) are currently working on an in-home demo program which should be off the ground within the next few weeks.

The 8c, an active speaker, might not be for you, but it’s one of the most accurate (in-room, not just anechoic) speakers available, work exceedingly well in untreated rooms. With that said, we do feel that the only way to properly evaluate whether a product is right for your situation is in situ.

Omega speakers are very musical. 

In my opinion Joseph Audio and Kef reference are safe bets, I ordered both without listening and they’re great

Having owned a Audiostore I would ask ,what is your other equipment, room size 

and $$ budget  all 3 things count in building system synergy 

for example if you have a Sonus Faber which is a bit warmer, or Wilson 

 all tubes would be too much of a good thing in warmth.,

that’s just a example , and also what type of front end Thst too can be tubey warm sound if you had say a Lampizator.
