Keyboard Magazine /February 2016 has the following very comprehensive four page review:

Korg Pa4x and Yamaha Tyros5

and another full page review on the JBL EON615 speakers

and....how Lennon and McCartney put their songs together....original arrangements by them written out. It seems Paul was gifted from birth.

Pretty much what everybody knew already in that the T5 is great OOTB but very limited in editing (Making it difficult to create an individual sound) but great ensemble section and pipe organ which separates it from others, whereas the Korg can be tuned to your own personal preferences making it easier to sound individual, all combined with better acoustic pianos, organs & style guitar parts. (Interesting how in spite of the marketing there was minimal difference between DNC and SA1/2)

Biggest surprise was the price differences in the US, as over here in Europe the differences are not that great, although the T5 is still the slightly more expensive.
