Well here is my take on this 4 way melee
Dali
Heard the Zensor 1 + Vokal + Sub = darn bang for the buck if you ask me for HT, also great for stereo listening in a small room.
Zensor 5 or Zensor 7 + Vokal + Sub = for bigger rooms (>40sqm)
=-=-=-=-=-=-=-=-=
PSB
PSB Image B6 + Centre + Sub = great for music, but something is missing with HT that can be modified with tweaking the tone controls.

Polk Audio
Polk RTiA3s or RTiA1s + Centre + sub = another bang for the buck for HT but is a bit more expensive than the Dalis for the same purpose
Odd Quirk: RTiA3 is more for Audio over HT, RTiA1s is more for HT over Audio if using a dedicated audio setup (integrated amp + CD player)
=-=-=-=-=-=-=-=-=
Bowers & Wilkins
B&W 685s + Centre + sub = another perfect HT and Audio match, only IF your AVR can handle the B&Ws in HT.
The only AVR that did deliver in spades for this group - a Rotel RSX, But it costs an arm and a leg plus your kidney and cornea.
The Polks, Dalis and even the PSBs are more unpretentious and 'social' when it comes to AVRs in HT mode.
B&Ws are a bit snobbish = picky with AVRs especially the low powered ones in HT.
Assuming you have a medium to high end [insert brand here] AVR, then the B&W will definitely impress.

The actual verdict will come from you since you have to bring your AVR to audition.

Heard these permutations:
Dali Zenzor 1 + Vokal + sub with a Harman/Kardon AVR265 (Thanks Xandrik! [ecks_xnm] of PDVD)
Dali Zensor 5 + Vokal + sub with a Harman/Kardon AVR360 (Thanks Architectural Audio!)
Dali Zensor 7 + Vokal + sub with a Harman/Kardon AVR360 (Thanks Architectural Audio!)
B&W 685s + HTM 62 + sub with an Onkyo TX-NR818 (Thanks Toyama!)
B&W 685s + HTM 61 + sub with an Onkyo TX-NR818 (Thanks Toyama!)
PSB Image B6 + Image C4 + sub with a NAD T748 (Thanks Spectra!)
PSB Image B6 + Image C5 + sub with a NAD T748 (Thanks Spectra!)
Polk RTiA3 + Polk CSiA6 + sub with an Onkyo TX-SR508 (Thanks AVShop/MLY!)
Polk RTiA1 + Polk CSiA4 + sub with an Onkyo TX-SR508 (Thanks AVShop/MLY!)
Of course things will change once you bring in your AVR hence the wisdom in bringing in your own equipment to audition the speaker sets in question.
