I spent October 2009 listening to 5400 versus Simaudio Eclipse and Andromeda. I prefered Sim products to 5400. Yes, 5400 has nice midrange, smooth, silky, and ravishes the ear. Sim products had liveliness, complete tonal range (esp Andromeda), dynamics.
When it comes to tonal balance it does not compete to above Sim products. Sorry I cannot comment on Accuphase. But I would think that Accuphase is superior to Sony, but that is a conjecture. All above in my opinion of course.
