Synergistic fuses in Naim Audio equipment

Ok, I can hear the dismissive comments already... £45 for a mains fuse? ... snake oil ... you can convince yourself of anything if you've paid that much... etc etc

But no, upgrading fuses is a very simple and fairly cheap way of pepping up you system. I was reminded of this last night after spending a few hours with a customer/friend who has a high end Naim set up. Naim systems are very difficult to 'tweek' they only really work with Naim sourced options .... this isn't a Naim sourced myth .. I've tried some really high end cables with Naim only to find that their own basic A5 cable worked better .... So, substituting fuses seemed like there would be potential for a wasted evening (in Hifi upgrade terms anyway)

We started of with a single 13a Synergistic SR20 fitted to the Thor mains distribution (one of the few of its type that works with Naim) ... Now, I've heard what fuses do before, but I still had a reservation due to Naims resistance to upgrades ... but the difference, even with just a single fuse, was quite spectacular....

Bass was much more 'sculpted from the solid' and vocals separated from the mix in a very natural way. Overall the kind of improvement brought about by a major component upgrade ... We then moved on to replace fuses elsewhere, which stepped things up again, not quite to the same degree as the first, but very pleasing all the same.

The next move here is to try Synergistic internal fuses ... which I've never tried, but according to the importer they make a bigger difference than the mains versions!
