I am looking for speakers that would fit a Marantz PM6005 amplifier. The difficulty is this: my walls are full of decorative stuff, which means that I must put the speakers near the ceiling and angled down. The speakers I have looked at (eg, Dali Zensor 3) are meant to be placed flat on (or near) a wall and not at a corner (so as to avoid too much reflection too soon). Are there any speakers *designed* for placement near a corner and at an angle? Thanks...
