Swapping Wilson Watt Puppy 6’s for open baffle Pure Audio Project Trio15 Voxative's

I would appreciate any thoughts form forum members on the following.

I am considering selling some Wilson Watt Puppy 6’s and purchasing a pair of Pure Audio Projects Trio15 Voxative open baffles http://www.pureaudioproject.com/product/trio15-voxativ-open-baffle-speakers/

The price differential is not that great (the trios are £5,250 inc tax in the UK) and so I could make the speaker swap with a relatively small cash injection.  

I am in discussion with a UK retailer to loan me pair of Trio15's at the end of February but there is a cost (refundable if I purchase) and logistical fuss to the process.

I like the Wilsons a lot, however the lower bass can get out of control at higher volumes (my room has raised wooden floors). My rational is that the open baffle design will put less bass vibration into the floor because the energy is dissipated more widely and not contained within a cabinet.

The Trio15’s also allow future upgrades (for example swap in a horn tweeter) and they will also allow bi-amping via the DEQX, which means I have an upgrade path, as funds allow.

The downsides I can see would be:

1. Buying new means there would be immediate depreciation.

2. I may lose some slam, which I enjoy with the WWP's.

3. I have read that that the imaging of open baffles is wider but may be less precise for individual performers?

I would be interested to hear from any other forum members who have made the move from traditional cabinet speakers to open baffle/Pure Audio Projects and any observations they may have.

Thanks very much.
