Yes, the G70 is an amazing instrument Diki...I could listen to it for minutes...
Seriously, your G70 would sound some good through the double Bose system...we ran an old second hand E-86 through them, and it sounded terrific...in my opinion, that's the way all arrangers should be amplified...lots of coverage, and excellent stereo imaging.
Have you tried your G70 with this type of setup?
I wasn't much of a Bose supporter until I tried the two systems (stereo).
I think it is, or more rightly, "they" are worth the investment, especially since it will be long term.
Plus, you don't need stands or monitors, so the stage is uncluttered,
