Does anyone know where I can get a pair of Mordaunt Short MS300P speaker stands from? I got one pair from RS but despite (or inspite, I'm not sure which!) they cannot get me another pair! Alternatively, does anyone know where you can get a good pair of satellite speaker stands that won't fallover when someone walks past? The MS300p's have a very weighty base which limits the top heavy effect! I have Panasonic HEP10's to sit on them. thanks in advance!
