Do I need to use filler in my speaker stands?

The monitors I referred to are my Lahave Mela monitors. I also have
SF Cremona Auditors (also fine, but the Lahaves are more natural and better in every way I can discern.)

And Roxy54-- believe it or not, I've go an old pair of Celestion SL6s I bought in 1993! Thanks.

Oh, about the rice, very interesting but I thought organic things like rice could rot or get moldy or attract insects.
I never heard this before, but it's intriguing.

Thanks to everyone.

Yeah, just to go tangential on my own thread here, but the little 30-pound Lahave speakers have a place in my heart such that I'll never sell them even if I the upgrade bug hits and I try something new out of curiosity.

I have many speaker I liked in the past that all did something special : Von Schweikert VR7s (percussion, mids in general), Wilson WP6s (detailed natural bass, layering, staging), Kharma 3.2s (coherency, the disappearing act, imaging, speed), Aerial 10Ts (easy on the ears sound all the time), Apogee Stages (completely real human voice reproduction and a 4th-wall-dropping in-the-room sensation that was amazing).

But, in tonality aspects, including bass quality, the little Lahave Melas are as good in all these areas and have that special natural and live sound with soaring/exciting but totally non-fatiguing highs and a deep satisfying non-soft bass and palpable super-natural vocals. So the Lahaves are my favorite as the total package overall of all the other speakers. I wouldn't have believed it if I hadn't had them in my room. (They were recommended to me by an audio-buddy.)

I actually owned all of the other speakers I mentioned. (I left out the word "owned").
I also had Piega P10s which had great imaging, too.

Thanks Paraneer! That's a new one to me.
