I replaced steel tubular stands with these. The sound quality improvement is stunning. I know that I sound like, pardon my language, an audiophile. I'm not one, I swear. I am a music lover.
The old ones were resonating like crazy with certain notes. In general empty steel tubes make terrible monitor stands. At minimum, they should be one piece tube cut to desired length and filled with something, e.g. high density polyurethane foam. But I am not aware of any producer that does this. So just get a pair these.
Also, they look quite stylish.
Just don't expect them to absorb much bass. You'd need much more foam volume (m³) for this.
PS. @Thoman, I wish there were some choice of sizes. Choice of all black colour would be nice, too.
