Just going by the limited amount of videos and information on the SD9 (But taking into account the SD7Audya on which it is based) it’s difficult to come to a solid conclusion, but I would say its chalk and cheese, so just go with whichever floats your boat. (There is no one arranger that fits all)
Until I try one I will reserve a final judgment, but it’s the Korg PA4x it’s got to beat, as the T5 is dead in the water due to the Genos replacement out this autumn (fall).

English Riviera:
Live entertainment, Real Ale, Great Scenery, Great Beaches, why would anyone want to live anywhere else (I�m definitely staying put).
