Harosha,
I had a PA4X. I thought the S1 sounded great with the 4X.
Do you like the Bose S1 as much with your new Genos? Some say the Korg does well in mono while the Yamaha sounds much better in stereo.
I’m using the S1 primarily at home right now with the Genos. I run left/right from Genos to the S1.
To me Genos+S1 = gorgeous sound
And, by the way, 15lbs...nice. 😊
