Cheap Plywood stands VS expensive manufacturer's stands

If height is the same, would it matter much?
I'm looking for some monitor size speakers (Spendor, Harbeth, ...), and most of them for sale do not include original stands which usually cost over $500 new. 
There are plenty of cheap stands at lower cost, but I wonder how much the sound would differ.
Anybody a/b'ed  on quality stands and cheap stands?

thx
