They are definitely detrimental to sound. Basically the covers form a giant ground plane, being parallel to the printed circuit boards. Forms a tiny but physically large capacitor which rolls off the top end. replacing the cover with a plexi glass sheet, gives the dust protection but retains the "openness" of removing the cover. The effect is even greater is you replace the bottom cover. which lies closer to the boards.
