Grit, I own Aerial 7B's and would trade them in a flash for anything from Dennis Murphy and Jim Salk. (In fact, I do also own a pair of Dennis' Philharmonics.) As Rod pointed out above, your B&W's and the Aerials are good hi-fi, and SalkSound speakers embarrass them, IMHO. (Please note that I haven't auditioned the Aerial 7T.)
Rest assured that, especially if you get a model with the RAAL tweeter, you will not experience harsh or shrill highs...just the most effortless, detailed, and elegant top end you've ever heard.
And yes, Jim's cabinet work is beeeea-U-tiful.
