In my search, at one of the audio salons I visited, the salesman asked me if I prefer "analytic" or "musical" speakers. I'd never heard the choices expressed that way, thought about it for a bit, "musical" was my choice.
In the process I auditioned some of the finest names in loudspeakers, but those which were characterized as "analytic" just didn't seem to float my boat. I found that most of them cause listener fatigue to set in quite quickly (even when driven by smooth sounding tube equipment).
As a result, I ended up with a new pair of Focal's that offered me exceptional detail, dynamics and sound stage, but didn't tire me out.
