its all in the Eq....makes a big difference ...thats why hearing it in person is always best.
Both keyboards recorded in mono, whereas his talking is recorded in stereo. Makes a lot of sense...

Additionally, the PA-4X or its recording level seems to be turned a bit louder than the Tyros 5.
Thast what i meant, point is this video is created by a reseller probably meant to sell more PA4x keyboards, and with Bonners being quite professional at these things, it might actually be on purpose..
