Bob (gdnrbob) has hit the nail on the head.
Since you have stated you want to buy your next speakers brand new, (or buy demo speakers, if you want to save a few bucks), you will therefore be buying them from an audio dealer. So, you really need to go to the closest city with a few audio dealers, so you can make a day of it listening to various speakers.
I recommend that you make appointments with as many dealers as you can, so that way, they are ready for you when you come in. And don't forget to take your favorite media (Records, CDs, etc.), with you to use for auditioning the speakers. (BTW, if you're into vinyl, make sure they have turntables setup for auditioning - some don't.) Figure on a couple hours at each audio salon, with an hour or two between dealers, to give you and your ears a rest. (If you start early in the day, you can probably get in three salons.)
Good Luck in your search!!!
