Jarnesque:
Yes, it's not that I'm unhappy with the 685s , just that the overall sound might be better with the BR2s if the WHFSV review is to be believed (did they mean Solo Mini + BR2s are better than Solo Mini + 685s??) and also that I might not be doing the 685s justice in this set up and with the admittedly pedestrian use I ask of them (like buying a Porsche just for the odd run to the shops).
Siting is difficult as well - I can only get the 685s 20cm from an interior wall, any further in the room and people will walk straight into them when they come through the lounge door. I have a fairly average and decent sized rectangular lounge but despite all the advice about siting speakers (not in corners, 3m apart, away from the wall etc.), I struggle to see how most people could put speakers in the ideal position in an average room unless you de-camp all your furniture into the bathroom and nail shut the odd door or two?! Mine are in about the only position they could go in my room unless I wanted to watch the TV in a mirror from the kitchen! I do at least have them on Z2 stands.
And that's the other thing that made me re-think the BR2s was that they're less fussy about where you put them.
Jarnesque, I think that's unfortunately your problem - I'm also in a smallish room and to my ears 20cm is definitely not ideal - you're getting good bass but at the expense of imaging.
I would definitely sound out the KEF iQ30s as their famed UniQ drivers make them quite versatile at siting - and imaging is their strong suit as well. In fact I regret not auditioning more speakers with the Mini before I bought it.
