A case that is 2,5" shorter and only .5" taller than sd7, with speakers, at 33 lbs..with basically same layout. I guess there's almost 9 lbs more good stuff inside, or heavier gauge housing. By my chart 7+ lb difference seems common between motl models and totl models. Still I wonder as components get smaller and lighter with technology a new 61 key arranger comes in at nearly 42 lbs. I concede that the sd90, the heart of the keyboard version, is 3.5 lbs more than the alternate sd40, but the sd40 doesn't have the full panel that the sd7 keyboard version does..
Add 6 lbs to a PA4x or Genos (76) for speakers and they're still in mid 30s..
So does it have to be heavier to be better?

I think it depends on your definition of "better". My Audya and Pa4X are heavier than my S970, and in this case it translates into a more robust and firm feel of the case, and, certainly, the keybed. Maybe some of this is merely perceived as stronger, since the plastics today are supposed to be higher impact resistant. Psychological or not, I will forego light plastics and keybeds as long as I can.

As long as I have known Mr. Bernie he was willing to carry extra weight to get the sound he wants. The last I remember it was a Kn7000, heavy, one of the first Bose, heavy and plus, plus, plus.

My viewpoint .. the heavier models are always better than their lighter models..

I sold my G70 to get a Pa800 some years ago, because it was a little lighter. The dumbest thing I ever did, outside of my second marriage to the accordion player.

NO, chas didn't tell Bernie to say that .

The accordion playing might have been the best part of that marriage ...

Actually, the accordion playing brought in extra bucks. It was two resentful teenagers that doomed that one.

I had a step child I nicknamed "the wedge". He was instrumental in ending that one..
