Ok, "issues" then...
Am a intrigued to try an omni (like MBL or GP) to find out if a such would enhance the listening experience (and yes that would be a little much to ask dirac).
But I’m unsure. A few listening test tells me omni’s could work rather nice for more quiet acoustic music, but not so much for music with a lot of energy. I felt the mids and highs just disappeared at higher volumes. What’s left was a bassy and warm sound but uninteresting.
They do seem to solve the problem with very closed mic’d singers you tend to get in your knees while placing the soundstage well behind the speakers instead of in front of them.
All reviews I read are so very positive - which make me a bit suspicious.
Sorry for these thoughts that have not so much to do with the op’s original question, but he or she seems to be sleeping anyway.
Maybe you know!
