Since its a silent slab I would assume to get the best sound out of Genos at home or live on stage you would certainly always have to use two speakers in stereo or 3 w/a Sub, or headphones, to take full advantage of ALL of it's great sound & style attributes, nuances, effects, drums, etc,?
Sounds like you should be getting a Genos. 😊
I don't think after all the demos, reviews, listening, reading, etc, that the genos although good for some is an arranger KB I would buy for myself at this time. The EA7 is definitely a keeper. Will I add another KB at some point for what reason I don't have any idea?....but, it's a possibility. Like I said in a previous post and after owning more recently a, Ketron SD7, Yamaha S950, S970, Pa3x, Pa900, Two KORG Pa4x's I am not in a hurry. Please enjoy whatever it is your playing ....Take care.
