David,
A very reasonable and erudite response, pointing out alternatives. You and Charlesdad are always helpful with your responses. Thanks very much... I will experiment.
I had my Dynaudio C1 Signatures playing for a week and loved the directness and detail of their performance, but I like the Jazzon's even more. The Cubes just sound more like musicians playing in the room and not like speakers playing music in the room, to put it one way. There is such an effortlessness and ease to the music with the Cubes and they love Don Sachs/Lynn Olson's new 300b monos.
