At the price point you are considering ($5000) there are integrated amps that are quite competitive with same amount spent on separates.
The issue I see is that your are considering the purchase of different speakers. There are many amps that can drive the Vandys that may not be suitable for others (Magnapans).
If I were building a system around a pair of speakers I knew were to stay, I would probably look for an integrated amp unless use of separates would allow for better system placement within the room.
Not knowing which speaker I might try in the future would cause me to go in the direction of separates. I would consider mating a tube preamp with whatever (SS or tube) best serves my current speakers.
