Tweakable Turntable For Complete Novice?
 

Hello all.
I'm new here and have never 'tweaked' anything in my life, well not hi-fi based anyway!
I have one of these (Hitachi PS-38 Direct Drive):

I'm trawling the net looking for tips on ways to improve the sound from this.
I have an Ortofon 510 cartridge on it and it's connected to a Cambridge Audio A1 amp and Gale gold monitors.

I realise this is quite low end but are there any tweaks I should be trying?

I've already decided to get a project or nad phono stage or something similar as the additional £20 cambridge add on doesn't sound at all good. I heard this turntable through a friends Wharfedale midi hi-fi and the turntable sounded so much better, so I reckon the phono stage and/or amp needs seeing to.

Also, would anyone recommend trying out things like record clamps, wooden cones etc?

Thanks for any tips in advance.
