Hi all
So I am now running Naim nova (50 hours run time) with kef LS50 meta speakers (over 200 run time) on kef S2 stands filled with sand.
Current cable 2.5m QED xt25 cables.
I feel I am lacking bass and although the detail is amazing I am finding it a little harsh.
What people’s thoughts ??

Naim NAC A5…….? Preferably terminated at the Nova end with the supplied Naim plugs.
To extend a little, buy yourself 2 x 3m NAC A5, get it decently terminated as suggested above - if you like it, keep it, if you don’t you can pretty much flog it on for what you paid for it, and you’re off to the races.
Otherwise, pester your dealer to try as many of his demo cables as you can and see if there’s anything takes your fancy.

Lacking bas with LS50 seem fair enough, after all they are quite small bookshelfs.
Experiment with distance to rear wall, and/or connect a sub at very low level Hz only.
I don’t understand why it should be harsh ?
What streaming service do you use ?
Your current cables are just fine but might get a slightly better/different result changing Brand and expand length.
I doubt thats all you need.
About the best bass I’ve had is with my current Kudos KS-1
Certainly more than NacA5 and new Linn K200 to my ears. 
Worth trying alternatives for sure (borrow or maybe buy s/h) but be careful not to assume all of the weaknesses you have identified are related to the cables.
I don’t know your speakers but think about how they are positioned maybe? Try unloading the stands? Little tweaks rather than big investment first. Might address the bass this way, but the harshness is perhaps another matter.

As others have said, experiment with positioning of speakers (push back towards front and side walls for more bass). Additionally move the listening position forwards and backwards. All rooms will create standing waves and it is possible you are currently sitting in a null.
If that doesn’t completely fix things then think about speaker cables. I have owned the QEDs and they can be a little bright.
I have also owned NAC A5 and, more recently, Kudos KS-1 (with a Nova I might add) and either will outperform the QED, particularly in the bass. I will say however longer lengths are better in my experience, say 4m or 5m.
Hi @Scooter71 , what’s the layout of the speaker positioning. I’ve got Ls50 metas and they’ve never lacked bass, in fact they can deliver really strong and solid bass. They are however very position dependent, way more than most.
Somewhat the distance apart, to the back wall from the rear of the speakers and to the side walls?
The answer is always Nac A5 for any speaker cable thread; minimum 3m lengths of course 
It will also solve marriage issues and get rid of verrucas.
NACA5 will also cure impotence .. What do expect from the Naim forum ..
@Scooter71 If your stands are filled 100% reduce to 75% Try NACA5 , Other good cables for KEF are WireWorld, Cardas, Shunyata.. Good Luck
You had the Kef’s before the Nova? What did you use them with?
They where second hand
I used qed speaker cables years ago, then changed to nac a5 and the difference was staggering. Nac A5 everyday of the week.
In my experience, the choice of speaker cable is speaker dependent. Ask a friendly dealer if you can borrow two or 3 to try.
Have you checked speakers are correctly wired in phase? That can instantly lose bass though may provide poor definition higher up which it doesn’t seem you’re having, but wirth checking anyway as its so easy both to get wrong and to fix.
Otherwise I’d suspect the room before the cable.
Before you do anything, allow the amp a good deal more than 50 hours before it settles. I’d come back after a couple of weeks and let us know then.
Whilst I agree that speaker cables specifically can change the outcome, ‘staggering’ is not something I personally have ever experienced. It’s the last thing I’d change after trying pretty much everything else to add that bit of fine tuning. Moving a speaker a tiny bit can make more of a difference imho.
@Winniethefoo has it nailed. Speaker cables do make a difference but generally more evolution than revolution in my experience. Do the free things around positioning, changing the stand filler, checking phase etc etc before anything else.

I may have to add that TRelx mentioned ‘years ago’. I am aware that older Naim amplifiers used the speaker cable as part of the circuit and were more sensitive to type. I do not have any experience with older stuff from the company so a difference may well have been ‘staggering’ by using a Naim recommended cable. I can’t imagine a Nova falls under this category though I may be wrong.
