Help! Nac A5 plugs does not fit Nait 2

Cut off the ears--they're a later development, and have no effect on sound quality.

the side with one lug is the positive end. The side with two lugs is the negative end. Ensure that the positive ends are on the outside with the negatives near each other when you manage to get them in place (so, reading left to right you should have Left Pos, Left Neg, Right Neg, Right Pos). This should translate (if wired up correctly) such that the NACA5 side with the lip on it is also on the outsides.

Old plugs had just the one lug if memory serves, with the other side having no lugs whatsoever.

I cannot fit the two negatives next to each other since they are both 2 lugs and they run into each other.

I then tried the two lugs and the one lug side by side but they do not fit either.

I think the best way is to cut the ears. As someone suggested. Hope it is safe.

Won't do no harm except to yourself if you arn't careful thats tough plastic.

You might be better with a junior hacksaw as apposed to say a knife

Let us know if you start painting in vibrant colours!

It is only necessary to cut the dual lugs off of the negative side of each of the plastic plug housings as the positive side single lugs face outward on the Nait and therefore do not foul anything.

I would disassemble the plug housings using a Pozidrive or Philips screwdriver and, as suggested above, use a hacksaw blade to cut the dual lugs off flush with the plate. The plastic used is quite tough and a knife just won't do.

IMO, the strain relief that is provided by properly seated Naim plugs is particularly important with the Naits as the loudspeaker output sockets are supported via soldered connections to the circuit board rather than by being fitted to the back panel. They are quite durable, however I have seen a number of Naits that have had one or more of their sockets rearward anchors broken free of the main board (most likely due to manhandling of the A5 while it is plugged into the amp). This is easily repaired, however it necessitates removal of the main board from the chassis to gain access to the boards underside for re-soldering.

Regarding the routing of the A5, there are two main options; 1) place a 90 degree bend in the cable within an inch or so of the plug such that the connectors are pointing straight in line with the cable (heating it with a hair dryer makes the job very easy - don't worry it won't break) and then bend it downward over the back edge of the shelf that the amp sits upon or, 2) swap the cables left for right (at both ends) and plug in upside down such that the cables extend upwards and then loop down to the floor (my preferred method although a bit more unsightly if your amp is on a top shelf).

Hope this helps,

Thanks for all the great tips.

Just curious, does everyone goes thru hoops like these just for a pair of lousy speaker cables?

More curiously, if these cables are specifically designed by Naim for Naim Amps which Naim insists that we use them, then why don't they fit in a Naim Amp? Haven't these gurus in Naim thought of trying it on their own machines?


Most curiously, why does it have to be difficult? Those plastic ears seems quite uneccessary. Or do Naim owners just enjoy the MacGyver tricks?

I think in this case Naim redefined the term over-engineering.

I did the upside down, right side up approach. Worked just fine. Apparently the ears were brought into being after the Nait 2 had ceased being. The design works on all later equipment. Everything on the Nait 2 is squeezed.
