Thanks Dave,

Your explanation makes sense, and could explain why Bernie's setup sounds better on his SX-900 compared to the pa4X

And funny thing, a few days ago, I watched a PreSonus / iLouds mini comparison video (below) .

My keyboard is setup in a small computer room, and the iLouds mini, being much smaller, might be the perfect fit. So even though some reviewers prefer the PreSonus, the size of the iLouds, and the fact the PreSonus has bass in the rear of the speakers, (may not be good for a small room) I may just take you up on that generous offer.

Would that mean I'd have to drive to Philly? I probably would, especially if Donny buys us breakfast
