Bookshelf Speaker Stand Difference?

When I think book shelf speakers, I have thought that the designated speaker stand from the same brand performs the best for a speaker.

For example, Focal Utopia Bookshelf - Focal Speaker Stand for this model.

Today I happened to have a conversation about this, and heard that as long as you use reasonably high quality/heavy stand (for example, Solid Steel Speaker Stand about 30lbs), there would be NO sound quality difference compared to using the designated speaker stand.

For speaker stands, benefits of designated speaker stands are

1) Aesthetic
2) Can be connected to the speaker

And... reasonably there is no sound quality advantage.It’s just matter of taste and convenience.
(A bit of secure connection too.)

How’s your experience?

And do you know any top quality speaker stand that I can use universally?

Thank you.
 But, get this, the Focal stands are about $2900!!
Which is a bargain considering how much the speakers cost. What's the problem?
" speaker stands need crossovers? Didnt know that " 

To the best of my knowledge mine is the only one that does.  It's a bit unorthodox. 

I had a totally different experience with stands and my Harbeth C7's and then HL5 Plus. I had stands for my C7's that are quite popular amongst Harbeth owners. I had them filled with sand. They came with small rubber dots stuck to the top of them. I started to play around with different devices on top of the stands like different Herbie's Dots, a solution that the stand manufacturer came up with and sold separately etc. Each one of them produced a completely different result, the absolute worse was the device provided by the stand manufacturer. I then traded up to the HL5 Plus speakers and put them on the same stands. After about a month I had saved up some money to buy stands made for the larger speaker. My dealer told me to check out some stands he thought looked nice. I agreed that they did look nice, my wife liked them so I ordered them. When I got the stands and first played music, these speakers totally opened up. They sounded so much better. The difference was night and day and it was immediate.

Here's what I think made the difference. The first stands had a solid top and the top of the new stands is open, meaning if my speakers are not on them and I look down at them from above, I can see the floor. The stands are more like a frame. I'm not sure if the result was similar to pulling your speakers away from the wall? I'd be curious to hear what others think about it.  I'm not saying this would be the case with other speakers but with the Harbeth it was the difference between liking and loving these speakers for me.

Please, can you tell us why you want to do this?
Now, I'm really interested.

We make a stand which includes a subwoofer and an up-and-back firing driver. The purpose of the subwoofer is self-evident, and the purpose of the up-and-back firing driver is to manipulate the reverberant field.

It’s called the Super Stand. We picked that name because there just isn’t enough hyperbole in high-end audio any more.

At this link you can see photos of the original version, scroll down a bit. The subwoofer is in the top of the notch, and that’s a coaxial in the bottom of the notch:
