Nait 2 Rear Panel

You need a hacksaw. You don't need the plugs for orientation as the Naca has a ridge running down the edge of the cable on one side marking positive. 

I think you are talking about Naim's right angled speaker plugs. I believe that they might be too wide for your Nait 2.  You can remove the pins from the plastic housing and solder the speaker wires directly to the pins. see image below.

Hope this helps you.

As suggested, use a hacksaw to get the tags off. Banana plugs are fine as well. I find that the having the cables at 90 degrees makes positioning of the Nait a little limiting.

Olive or Chrome Bumper vintage?

Welcome to the world of beautiful music. The better the source the more incredible your Nait2 will sound.

Badlyread - it's olive.  It's in mint condition and it looks incredible.  That said, I had never liked the chrome livery until I started looking at Nait 2s and I must admit the 2 in CB looks the part.

Badlands - Coincidentally one end of my cables is terminated with the speaker wires soldered to the pins, exactly as shown in your picture.  It's just that right now those ends are going into the speakers.  So I should reverse the direction of my cables and plug the pins into the Nait 2 while inserting the plugs into the speakers?  The reason why I am so focused on this is a friend of mine who used to be a Naim dealer was quite sure that plugs should be used going into the Nait 2 in order to prevent the metal pins from accidentally coming into contact with the metal rear plate and causing a short.  Another reason he recommended that was plugs should theoretically hold the pins more firmly in place and reduce any excessive movements which could break the internals of the Nait.

Gary - yeah, this thing is magic.  I get what all the fuss is about now

A good-sized pair of large-gauge wire cutters would also work. In the not-so-distant past, I kept a box of old-style dual-plug bases (sans double tag on neg side) specifically for that purpose (to replace the later bases for NAIT1 / NAIT2).

Using the dual plugs does helps to insure that you won't short out the pins, though there is also some additional cable dressing required to insure that the cable itself is not rigidly coupled to the pins themselves.

It is a well known fact (often denied by those in the know) that the Chrome Bumper Nait 2 sounds better than the Olive. Having owned both I have a CB version.  

Enjoy this magical little box and if it has not been serviced then give Darran @ClassA a ring. Fantastic job every time.

^ I have both from the 80s and I can't say I agree about the CB sounding better.

It's no good declaring absolutes here.  Sample variation and time will have widened any differences to make saying that one is better than the other completely meaningless.  Unserviced CB NAIT2 vs. unserviced Olive NAIT2?  Who knows how their respective performances may have deteriorated?  The Olive though will automatically have the advantage just because it's younger.  My own CB NAIT2 was totally rebuilt by the factory with new output devices and it trounced an otherwise very nifty Olive version.  But who's to say the gap won't be closed if the Olive unit had been subject to the same amount of work.  The very first batch of CB NAIT2s did apparently have a few teething problems, and a handful that went out perhaps did under perform, but all (apart from the PCB error) should by now have been fixed with proper servicing and updates.

I would just like to point out the  at the end of my statement. All tongue firmly in cheek. The innards are basically the same as I understand it. The CB just looks so retro cool, who cares what it sounds like? 

BR, I was going to say (but didn't in my last post) that all else being equal, buy on cosmetic preference.
