Speaker Help-B W,alon,AudioPhysic,Aerial

Hi All,
I am planning to upgrade my speakers in an attempt to obtain more realistic vocals and improved soundstage, while retaining relatively fast bass (and maybe go a little deeper). I am looking to spend between $2000 to $2800 (used), and I had decided to go with B&W M802SIII (inc. sound anchors). However, in researching this a little more, I am also considering AP virgos, Aerial 7B, and Alon V MkII. My current set up is a Pioneer PD65 with Assemblege DAC 2.6 and D2D-1, Adcom GFP750, Aragon 4004 MkII, and B&W M803 SII (with sound anchors). The next upgrade will probably be the Aragon, but I plan to stay with SS. I believe the 802 will improve the soundstage over the 803 due to its isolated midrange unit, but I am not sure that there will be much other improvement. The AP are perennial Class A, and the Alons seem to be highly regarded for their open baffle design. I listen to rock (not metal) and blues. Any help would be appreciated. Thanks
