Been living with the A3's for a little over 2 years. 8 feet apart 8 feet to listening position, 2 feet off back wall, 2 feet off side walls.
The magico apod footers, in my case with extra long spikes to penetrate carpet and padding made a large difference, both in imaging and clean tonality.
Also found big improvements with a coupla sound treatment panels between the speakers.
Without footers and panels, good, with-->much much better, possibly great.
