Thanks all for your responses! It's great to see different perspectives.
To answer your question Litespeedaudio the sound of the Mini Utopias with the Pass gear is fantastic, albeit a little lighter weight in the sub 45 hz but that's the speakers not the amp or pre. I have always preferred a tight, focused, some would say fast sound and that is indeed what I have. The reason for posting was sort of what Philjolet alluded to. Save some money in one place and apply in another (a sub for example). But I don't want to make a step backwards in sound quality to save money.
