ASR Mini Basis, Simaudio LP5.3 or Heed Quasar ?

Hi.Has anyone compared them? Used prices can be close enough.
I understand that they all sound very good but quite different. Do they really belong to the same class?
I may want to get one of them, and I don't like upgrading too often. We got German, Canadian and Hungarian stuff here.
No American, British or French this time.
At present I would use it with Goldring 1042 MM/Nottingham Spacedeck&Spacearm, but it should be able to handle really good LOMC.
Another question is, do you think that any of them is equal or better than Rowland's phono card in Concentra I, Concentra II and Concerto integrateds ? I am asking because that's what I am later most likely going to upgrade my Audiolab 8000LX to.
Would appreciate your thoughts, ideas, speculations etc.
