Yes, please get your Kef's on proper, sand filled stands and in a listening triangle for proper listening. Whooshing is usually a setup issue. I do not believe it is sylus (that is usually dulling of the sound) but you can certainly try it if your at high hours.
First make sure your table is level using a small bubble level, check your stylus tracking force with a scale, email U-turn, they can send you a protractor or you can print one out to check your alignment unless you already have one , and check vtf using the straw trick.
I would also recommend some sort of isolation at some point. One other thing your cable run form table to receiver looks on the long side, usually table to pre should be as short as possible (0.5-1 meter) with a good low capacitance cable.
