Do I have to spend $4000 plus to get a better sounding speaker than GET model 7 ?

I have owned a pair of Golden Ear Technology 7's speaker for almost 3 years. I think they sound very good in my current set-up.  I bought them unheard based on the rave reviews they received at CES 2012. My concern is that if I was to invest in a speaker that is $3500-$4000, it may prove to be only marginally or fairly better. I am not saying that the GET's 7's are the best bargain in audio at $1395.  My experience with them is they are  very accurate with low distortion, but don't throw a particularly wide or deep soundstage. 

I have considered( not necessarily auditioned) Revel F-206;  Focal Aria 936;  Paradign F85;  PSB T-2';  Ryan 630;  B&W CM9S   Dynaudio X-34;  Duevel "Venus"  Audio Physic Sitara 25 and Tempo 25  All of the indicated speakers (except AP and Duevel) fall in the $3000-$4500 retail price range 

ProAc floor standers are off the scope in price, (often, even used)   Anything I buy will be used, because California sales tax is 8.5%,  and I can stretch my dollars buying used. 

Any recommendations are welcomed especially if based on you own experience with a particular speaker or brand.

Thank you, S.J
