PrimaLuna EVO 400 or Raven Audio Blackhawk integrateds?

5 years with the  PL HP. If you're going only on internet suggestions, with articles,specs, graphs..whatever, then read as much as you can. 

In the end, it is subjective. The 1038's can sound great with many amps, and the PL is one of them. Hearing them in your room won't replace endless forum "I heard them with..." 

The Raven appears to be good stuff, but the PL possibly edges it out  with feature/value. Final SQ is a personal thing. Easily matches build quality, though Raven looks like it may have the edge with a few nicer, components? 

I sold my PL Dialogue Premium, non HP looking to get the Focals to their potential...

What was it lacking? Did you try different tubes-KT88/150's?

Demo the amps. You're only out shipping for what doesn't make the cut. The PL will have twice the power.
Perhaps the Raven's "better" components/transformers will make up for less power but you will hear it as acceptable?
