NAC 282 + Hi-Cap + NAPSC

You're correct. With one HiCap PS you need the link plug in place as you point out. If you are using 2 HiCaps or SCap the link plug is removed.

See section 10.7.1 Power Supply Upgrade Options of the manual.

+1 for the link plug.

Once in place enjoy your excellent new Pre amp 

Correct

withouth the link plug you can only run: 2 x HiCap or SuperCap

Thanks for the replies.

The second Hi-Cap option had not occurred to me.  As it happens, I have one that I am intending to use elsewhere in the house but for the time being I could keep it run-in on the NAC 282.

What would the connections be?  For now I have a Hi-Cap connected to the bottom-left of the four power sockets on the NAC 282, and then a cable from the Hi-Cap to a NAP 250.  What connections do I make for the second Hi-Cap?  I am guessing top-right on the NAC 282 (marked Upgrade 2) to the fourth (last) socket from the left on the Hi-Cap?

Best if you find a PDF on Naim's website called 'Connection Guide'. 

It covers most common connections. I use it all the time when assembling or changing something. This way I don't have to remember it

This may help.

I was a little confused at first since your profile says you have a NAITXS.

However here's a link to the guide Adam mentioned.

To avoid lengthy explanations the connections for two HiCaps to a Nap 250 are on page 13.

By the way I found the second HiCap was better served powering the Stageline with the other powering the 282. 2 HiCaps on the 282 wasn't  much of an improvement. Powering the 282 with a SuperCap was a vast improvement.

Thanks again for the replies.  The connections are now clear (and as I expected, which must mean I have learned a thing or two).  

My profile is not up-to-date.  The NAC 282 / NAP 250 combo is new.  The Nait XS will move on to other duties elsewhere in the house and in due course I will power it with Hi-Cap but that requires some re-organisation in the room in question. I also have a Nait 5i (non-italic) which is probably surplus to requirements.

I will try the two Hi-Caps on the NAC 282 and if nothing else it will keep the second one warm till I'm ready to use it on the Nait XS.

If I recall correctly you need to ensure both HC's are very close in vintage, amount of use etc.

I used 2 on an 82 many years ago...Not worth it from memory. SC much better.
