Hovland Radia, Pass labs xa30.5 or Chord SPM1200c

I am looking for a new amp for my Monitor Audio Pl-300's ( wil sell them and go for Pl-200's, I have a PLW-15 as well. I use a Meridian 800Daxv4 as source. I can use it as a pre amp like the 808i as well. I have own the Pass labs XP-20 and XA-100.5, 60.5 and xa30.5 as well. But the preamp of the Meridian is very good in use without a highend preamp. I did this before. I use Nordost Valhalla as speakercable, and Valhalla powercable for the Meridian. I will use a Purist Audio power cable for the power amp. What will be the best choice..
