Well scratched the itch... XA60.8 monoblock
compared to the XA30.8 more of everything
especially finesse and dynamics
finesse with more separation of detail and hearing further into the recordings.. even poor flat recordings have more to offer which leads me to are there bad recordings or simply gear unable to dig it out.
dynamics are easily a step up from the already excellent XA30.8
IMO the XA60.8 press scattered about the internet is real.
