im getting unwanted colouring in voices and other slight distorions when i place my f80 on a table and even on my atacama nexus speaker stands but i seem to be getting a perfect result when i place the f80 on my dad's alphason av stand but obviousley i cant nick that for myself so basically what should i go for? i was thinking along the lines of Audiophilebase StarBase or Custom Design Concept AV,
