@yyzsantabarbara I have been struggling with the stock stands (very annoying little things) so I have decided to design and built my own stands.
A layer os felt is between the speakers and the vertical plates and some felt round adhesive pads are on the feet.
The height is exactly what Magnepan suggests.
So no problem in this department, because the sound improvement is immediate… but I continue to find the treble output level too high for my taste.
