These are my observations listening to Grapelli and Menuhin and a Album by Robin. a classical Jazz and new electric type violin.
Very detailed soundstage, even at my age and hearing I was mesmerized. It sounded like the album members were right in front of us (a friend who is university trained music major Violin and Piano) No tunneling of the Bass, it seemed to envelope the whole room, when a measure stopped for a moment and another instrument came in there was dead silence, no electronic BS The highs and mids were articulate and you could hear the piano hammers and the violin bow.
I know the guys with the M2's etc. have it better but these are the best I have ever had.
