Hi Squeak,
I listened through DS-8 Bi-Amp Monitors and headphones(RH-300,I believe).The Roland rep,Danny Doiron,is an old friend,and I actually used to do some demos for him way back when the E-70 and subsequent models were introduced.
I also tried the new VP-550 Vocal & Ensemble Keyboard which was way cool. He didn't have a Juno-G.
If I was in a band,or doing some studio work,the RS-70 might be handy for "color"sounds as it does do analogue quite well.
I'd be tickled to hear some demos.
All the best,
Ian
