Short answer: the GR-Research NX-Treme, by a wide margin. It is #2 of 228 and radiates in all directions for a huge soundstage, though it is very tall and needs GR-Research open baffle subwoofers on each side. The Revel Concerta2 F35 costs $900 and its F3 of 61Hz and F10 of 39Hz mean you still need a subwoofer for real bass.
Buy the GR-Research NX-Treme when sound quality outweighs the price for you, and the Revel Concerta2 F35 when the price outweighs sound quality instead.
