DeVore O/93 or PureAudioProject Duet15 for a First Watt SIT-3?

My speakers are named in the opening message. Are Avalon Indras, a top speakers perfect for 89db listening, less for 69db night. 

The room is 19‘x12’ and 16' high (part is 8' hight).
There are bookshelves, a big sofa, an armchair and a carpet on wood floor.
Speakers have 5‘-6’ behind.
The listening armchair is 8‘ from the speakers (behind me I have 10’ to the back wall).

For me it is really important to have a warm sound, a wide and deep stage even at low volume.
The Avalon Indra are great, but they sound best at medium-high volume.

The position seems strange, but it is the result of a year of micro-movements of the speakers. If I increase the distance between them you can hear the music coming from one speaker, whereas this way there is more perspective fusion.
In the past I also had a MiniDSP, but then when I did the acoustic analysis it turned out that the Indra's performance is very linear and there are no holes or emphasis, so I removed the MiniDSP...

And for classical? 

Are PAPs more difficult to place in the room than DeVores?

Friends, I feel like we've gone a little off topic....
In the end I would have decided not to get an OB but to replace the Indras with the Orangutans. 
The dilemma now is between the O/93 and the O/96 (apart from cost). Which ones are more suitable for nighttime low listening?
