Hi, Just upgraded my router to the Bt Halo. It comes, as usual with a switching PS.

My questions are: 1. Would I notice a difference in upgrading to a Linear PS? (From what I've read - the answer is 'yes').

and

2. Which cheapie LPS would anyone advise? (I'd be using it with a Rpi/Allo combination - and Apple airport express). I have some of the Ebay/Chinese LPS driving other units and found them OK) but wondered about 'benefits-for-bucks'. Are there units that can smooth the 12V SMPS output? (I realise that these may not not stop the dirty noise being fed back into the mains).

Thanks,
