As much as I have enjoyed Magnepans in the past, they have several limitations for the OP.
For one, they are very demanding of amplification. This has been documented ad nauseum so I won’t get into that.
More critically, they inflate the image and are not what I hear in a concert hall. In my dedicated audio room, even set up ideally with room treatments, they were limited in this regard.
My Tekton DI’s recreate a much more precise and realistic recreation of a concert hall. Instrument location, depth, instrument size are all much more accurate. One can debate what accounts for this--wave launch, back wave interference, among others.
Right now I am listening to an old CD, An English Christmas, performed in Westminster Cathedral. Choir, brass, thundering organ. Magnificent! (My DI’s are augmented by a pair of subs)
I have had the pleasure on hearing music in that cathedral, among others. My current system transports me back to that place and brings a smile to my face.
Best wishes on your search.
P.S.--virtuoso violin performances have sounded great on the DI’s.
