New house, some questions on an upgrade

I've bought a new house and my UQ2 and System Audio Aura 1's have come along with me.  The Aura 1's are a real gem, fast, punchy, not too much bass and were perfect when I was living in apartments. And I just love the qute.

The main living room (4.8 x 4.4m) is where I'm planning to listen to music and watch movies via my projector (with the requisite white wall!).  For video I've a few sources via a HDMI switcher, audio de-embedder and optical delay fed into the UQ2.  At the moment the Aura 1's struggle to fill the larger room with anything bass-y at all. 

I now have a small study (about 2.5m x 2m) that I will be using a fair bit (both for work and personal projects).  I previously used Arcam Musos with a Musical Fidelity V90 amp which hasn't really been a success.  I'm planning to sell on the V90AMP and keep the Musos perhaps for the smaller living room.

My current thinking is: put the Aura 1's into the study, and buy some nice floorstanders for the main room.  I auditioned a few options some months ago: the Quadral Style Chromium 6, Spendor A2, but heard both on a Uniti Atom rather than the Qute.  But I'm still unsure if floorstanders are a good idea in that room at all.

The real question comes regarding amplification: 

Option 1: buy a used Uniti2, SuperUniti, UnitiLite for the main room, bring the UQ2 into my study.

Option 2: buy something like a Cyrus 6XPD (which includes USB DAC) for the study, leave the Qute in the main room,  go for high-efficiency speakers (like the Quadrals) or add a NAP 100.

I know auditioning is necessary for equipment selection, but I could do with some advice on even what overall plan to go with.
