Go to speakers website, look for dealers within your zip code.
Easiest is local audition.
But also consider buying online from places that offer a 30-day return, especially free returns.
30 day free shipping & returns would be Amazon (direct, not 3rd parties), NHT, Aperion.
30 day NOT free shipping & returns would be Salk & Ascend.
I like KEF, Revel, NHT, RBH, DefTech, Rythmik.
I bought some Philharmonic 3 speakers, but haven't gotten them yet, but have heard nothing except awesome customers reviews.
For subs, I recommend Rythmik FV12 for $500, which is the only Direct Servo sub for $500.
One example of speakers would be NHT Absolute Zero system. The Absolute towers are $500 each, Absolute center is $300, and Absolute bookshelf (surround) is $200 each. Or you could get the SuperZero for $100 each for surrounds. You can buy from NHT directly and get the 30-day free in-home trial.
