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

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.

Paradigm Persona 3F or 5F in white (or custom colors!). They are gorgeous and sound great (adjust the toe in to your liking). Well reviewed high value speakers built by a very reputable company in Canada, with a long history. I have the 3F and love it! You may need subwoofers if you have a large room, but those can be hidden.
