Seperates vs Integrated at $2000

I would like to hear from members that have moved from an integrated to seperates or the other way around . Given the same approximate value, @ $2000 total used, is one configuration beneficial over the other ?
I know that this has been discussed elsewhere but not within the context of equal and specific values .
I would be listening to fast dynamic music such as classic rock and contemporary blues, near field and in a small room . Low level characteristics are important .
Can anyone help ?
