I listened to Arro, Sttaf, Hawk and Forest three years ago and bought the Hawks. Having said that I am re-thinking my decision although that is based primarily upon room size/room dynamics and not the qualities of the speaker.
Here is my summary - this is only my experience at a particular dealer and in my room at home and is not meant to be anything more than that:
The Arros are remarkable for their size - in a small room with decent acoustics they are shockingly good. Clean, detailed, airy, surprising bass - wonderful really. Can't imagine many similarly priced "bookshelf speakers" being this good. Maybe the best sounding of the lot to my ears but only in a small space. Can be located close to back wall and that maybe even helps this speaker in some cases.
The Sttafs and Hawks I found to be fairly similar despite using different drivers. Both very musical and by that I guess I mean balanced and easy to listen to. Hawks slightly better in the bass and a little brighter in the treble. Again, both these speakers shine in smaller environments - the Hawks in my large room have useable bass to just under 40 Hz and I have added subs as a result because I miss the lower rumblings when they are not there as it turns out. Also don't think the Arro, Sttaf or Hawk are very "fussy" speakers - at the dealer I placed them close to walls, away from walls, bi-wire, single-wire, expensive wires, cheap wires and could tell little if any difference in any case and I suspect that all three models would sound superb in the right environment with a nice tube amp - indeed the TAS reviewer of the Hawk claimed he "drove them with ease" with a 32 watt tube amp. My Hawks are being driven by a 150 watt Classe. All three models I think benefit from some lead shot in the base.
The Forests clearly had more dynamic range but seemed a little drier to me - could have been lack of break-in at the dealer or an electronics mismatch - not sure - maybe they are just more analytical or true to the source. Whatever the reason they didn't capture me to the point where I was willing to write the check for them.
Hope this long-winded message helps.
