Proac SM100 speaker stand?

Current Target HR or MR come to mind.

Years ago the Target "R" series were the go to for Proac.

I have 20 year old HR's (used with Castle/Reynaud/KEF) and feel that they would be fine VS the more expensive MR's.

Solid one piece welded steel construction that does not leak "fill".

Sound Anchor stands are the best available in my experience and IMHO.

Sound Anchor Speaker Stands

Target MR stands are really good. Fill them with sand and you're good to go, or you could use lead shot.

Is there a way to get a hold of them in Europe?

+1 for Sound Anchor.
