My wife weighed in…she wants piano white tower/bookshelf

PMC stand mount or floor stander! Great base from very small enclosures. Outstanding WAF!

Depends what components you use with the Devilles. I’m using all Shindo , amp , pre amp and MrT. with 2 Rel S510 subs and believe me you would be quite impressed on the SQ . Everything is cabled with Luna red series and the synergy is just fabulous. Every system takes time to build and believe me I went also through the path of trial and error until my ears were pleased to what I loved to hear. My wife and I just can’t stop listening,absolutely no fatigue but pure enjoyment.

FWIW, while I love the looks of the Estelon Aura, keep in mind that it is bottom firing, not bottom ported. The woofer is facing downwards, so it generates a lot of bass toward the floor which also dissipates to the rear of the speaker. It is recommended that the Aura are also placed quite a distance from the walls, or else it will sound boomy and muffled. A number of the reviews cover this. Many of the speakers being recommended are not paying attention to your room and living constraints. 

KEF Reference 5 Meta White/Gold... I'm sure you have the electronics to push these around.

How about a set of Martin Logan towers? They make em in white and a pair of their top end model is approx 5500. They are said to sound very good and their gloss white finish and cabinet work is rated highly.
