Shakey, yes I have heard about limitations of open floor spaces. However, when I moved my audio system from a small room to this open space (18 years ago) I found the open space distinctly better. It allowed the music more breathing space, kind of like a church or cathedral. (I had a Dennis Murphy speaker + sub back then.)
The room does have a carpet, thick enough that I think I need longer spikes than the ones the X3s came with. I'd welcome suggestion, and also for unobtrusive acoustic treatment.
Heavy drapes and overstuffed furniture is not going to pass muster
See a photo of the space (ignore the clutter from unpacking the X3s and the subs from the old speakers). There is a glass french door to the garden on the left and large glass solarium to the left at the back. Right above this space is an open study, also with glass doors.
Musicdre, the Bricasti DAC+streamer is fantastic and I like that it doesn't need a separate preamp. Bought it at an impulse when a good deal came along and haven't compared it to the recent raft of new dacs.
