Primaluna separates or Integrated?

Im planning to upgrade my system around a recently purchased gorgeous sounding Primaluna CD player and my trusty 25+ year old Linn Sondek LP12 turntable. I am very interested in experiencing Primaluna amplification and am interested in advice of which route to take of either the Dialogue Premium Integrated or the Prologue Premium separates. I admit that I have not had the opportunity to listen to triode vs. ultralinear which seems to be the most significant difference between the two options.  Thoughts and opinions?
