IMHO omnidirectional speakers present a wide, deep sound stage but smear imaging. Vivid Giya series is my recommendation. Others I have heard are Borrensen, KEF Blades, Raidho, and Wilson. My experience is also electronics play a critical part. I did not realize the full potential of my Vivids sound staging and imaging until I upgraded from Krell to Burmester. Eye opening. Also power conditioning made a significant improvement in realizing the full potential. Finally, follow the well written recommendations from @audiokinesis and @mikelavigne - gentlemen, well said.
Looking for the next level in imaging...
I enjoy my system every time I sit down and listen. But as we all do, we get the itch to seek improvement! I am intrigued by Omnidirectional speakers such as MBL’s, German Physiks etc. and breaking free from the head in a vice sweet spot to get better imaging throughout the room and better the imaging in the sweet spot! I believe changing the speaker will deliver on this quest! What speakers would you look at? Or would changing a component yield the result? Has anyone gone from the traditional dispersion speaker to an omnidirectional?
current speakers are Martin Logan Ethos
budget $20-30K...could stretch if something is exceptional
