Did you put the little tiny rubber feet on? Before I put them on, I did get some vibrations.

No, they are not angled up. They have a pretty impressive dispersion field and I have less than 10 degree angle. The bass is probably what makes the difference in soundstage. When you don't have anything to "anchor" the perception of position, I find it is hard to get good soundstage. I tried this once (2-3 months ago) with the M80s by setting their xover at 150hz and shutting off the sub. It sounded airy and, altough I could pick up at all the instruments as well as before, they felt ghostly and unreal. With my AB up, it wasn't anywhere near as drammatic, but it feels similar (I just tried by raising my 9" with kleenex boxes--actually, they were "noname" tissues, but I don't think there is an audible difference).

Did you try with mouse pads under them?

Curious to explore this more (as long as you're the one doing the job!).

I did indeed put those tiny feet on. I wish I had the bigger ones like on the amp.

I don't have mouse pads. I got rid of them when I went to a thumb-style, roller ball mouse.

Did you try putting your thumbs under them, then?

Just realized... Weren't you supposed to use your **brand name witheld** subwoofer?

Yep...I am indeed using the Sony 150W sub that just won't die. I thought I killed it when I was doing head-to-head comparisons with the 600. It smelled like it was cooking and I bottomed out the motor so bad I thought it would come shooting out the port in the back . But it's still rocking...because it wasn't designed by Sony.

It sounds just awesome for this application in my 1000 cubic foot office.

Hey, they came with rubber feet? I need to check the box again.

What I'm starting to hear here is that I should just use these on the computers. That means I need to dig out my desk... and probably disconnect the M50s from the computers.

Tiny, tiny transparent feet; they're easy to miss. The same that comes with M3s.

M50's are your current computer speakers?

Ken,

The pads are in the plastic bag with the user manual.

Pretty much, although they're not positioned at all right. I usually use headphones. They're in the same room as the computer, so why not hook them up?

Tex: Found 'em, thanks!
