Mini Utopia

There is an golden rule: "The ideal height of the loudspeaker and speaker stand should place the tweeter at ear level when you are seated in a listening position" (taken from: http://www.plateaucorp.com/5keys.htm). So, take measuring tape in hand.

P.S. Regarding some measurements, steel filings are the best filler for speaker stands.

When it comes to stands a speaker like that deserves a good one and IMHO best out there are heavy mass Sound Anchors.What height you need and how many post (three or four) would be up to budget but Call Bob Warzalla at Sound Anchor.Especially if you have wood floors the more mass the better (some lighter stands can be filled with lead shot).Then use carpet spikes (if you have carpets) or small stand spikes and use protective cups for floors if need be to decouple from floor.This can make huge difference.But I have hear Bob's stands (which were absolutely required equipment form many models over years even floor standers like B&W 800 series) and have heard his sound better then OEM stands from manufacturers.Not I'm not with his company and he's not my cousin.it's just he knows more about them then anybody out there.They aren't cheapest but again they are the best.
