Looking for thoughts on Sonus Faber speakers

Dynaudio Contours might be a consideration for you. 

I was able to hear the Sonetto VIII the other day and they seem to me like they do exactly what you are talking about.  The vocals are so nice. 

SF Olympica iii is what I use. Discontinued and can be had at great deals.does everything you describe and sound amazing even at low volumes 

op

sonus fabers qualify for the type of sound you seek

past, higher level s-f’s were wonderful with classical and vocals, if they could be criticized, it was they would not ’boogie’ and sometimes smeared transients on more ’exciting’ music

more modern higher level s-f models seem to have cured that ill (of being too smooth and refined, dark) and play with more vigor when called on to do so

still, s-f’s will never offend with bright, piercing treble or a ’too forward’ presentation

other speakers in the same school of sound would be harbeths, vandersteens, classic spendors, and, at a somewhat lower level of resolution, wharfedales

It sounds like Sonus Faber are the perfect fit for you. Once I turned from being infatuated with planar speakers for over thirty years and wanted more realistic, balanced speakers I got SF. First, Cremona, then Olympica 3, and now Amati Traditional. I can't speak too highly of them. 
 

I agree with @soundwatts try and find a set of used Olympica 3. Their performance will be up another level.

On the other hand, I had purchased the Cremona as experiment... which was very short lived. Nearly as soon as I had them in my house I knew Sonus Faber was what I was looking for and I immediately ordered the Olympica 3... of which the first shipment was on a ship steaming towards th US at that time. So if you buy from a dealer like me, he will apply all the cost of the first pair towards an upgrade for a year or so. Couple be a good gateway. Each level in SF nets significant sound quality improvement.
