When you buy Levinson separates you are able to mix and match passive speakers until you find the match you prefer. When you buy a powered speaker with a plate amp you have the ability to mix and match preamps. Whichever you prefer is up to you. I have passive and active versions of the Paradigm Reference 20 speaker and I could never get the same bass extension with the passive speaker, regardless the amp. If I already had $20,000 monoblocks maybe they would sound better matched with the passive Paradigms in the soundstage or the mids. At the end of the day it would be "different" and is a matter of preference and budget.
