Naim Fraim Stacking Order

I would switch NDX and 282. and compare.

Thanks for your suggestion, MangoMonkey.

I will surely try to switch between NDX and 282.

I intended to install the tall shelve at the lowest level (above the base) to cater for my XPSDR, for better heat ventalation perhaps?

Or do you have better suggestions where to install the tall shelve?

I wouldn't put the napsc on a shelf. Place it on the floor as far away as the lead allows from the rest of your gear.

As for the rest. Xps bottom shelf. Normal shelf with hicap. Then tall shelf with 250 on.

Then as mm suggested demo the sources. I run my pre (252) above my ndx

why on earth would you want to do that!

I would definitely put on a shelf with any other half width boxes, and neatly coil the captive DC lead with a wire wrap if too long

Although I can't explain why, I too have learned that keeping the NAPSC away from other PSUs & components is a good thing to do.

Quite. I really don't understand the fuss around positioning the NAPSC.

Keeping the NAPSC away from which component, specifically? Currently I have the DAC at the top, followed by the NAC 282, then the NAP 250 DR. The Hicap DR and NAPSC share the same shelf at the bottom of the rack.

The NAPSC will be fine next to the Hicap.

Guys, I just purchased a used Naim Fraim with the configuration of 1 base, 1 tall shelve, 3 standard shelves.

My Naim equipments are, NAC282, Nap250DR, HicapDR, NAPSC, NDX, XPSDR.

Need your advice whether my intended stacking order is correct.

From top to bottom shelves.

NDX

282

HicapDR | NAPSC (same shelve)

250

XPSDR

Appreciate for your advice!

FRAIM installed by my dealer a month ago - LP12/NDX/282/200/HCDR & NAPSC/STAGELINE & NAS -

NDX above 282 is the way he set it up

Moving the 282 at the top, to keep it away from the Hicap or the 250?

interesting - i found the best performance albeit subtle the other way around. My 252 on  top shelf with the NDX below it... I really think the NACs truly sing when in the clear and on top.. and of course it might even be due to the more simple cable dressing you can do. Clearly if you have a single rack and an LP 12 you might need to compromise

I edited my post after i looked at your profile. I thought you had a Naim DAC (Hence the suggestion to move the 282) but see you had a Chord instead hence the edit. Still worth moving the 282 up if that doesn't restrict access to the Chord when it's on a lower shelf.

Apologies for the confusion and thanks for the suggestion. I will move the 282 up this weekend (I didn't bother to fiddle with the placement all this while).

Say if I have the Naim DAC, what is the logic in moving the 282 up and the Naim DAC down?

No worries. Moving the 282 to the top stops it having mains transformers above and below it. The Chord uses a smaller switching supply so less to worry about here and moving the 282 away from the 250 would be a good idea. Let us know how it goes 

Right thanks. If that's the case, moving the 282 up might help as currently the 250 is just below it, and it has a pretty robust transformer.

I always had both preamp and power amp aligned together as aesthetically they look better, unseparated.

Yes best to keep them apart - ok for amps like the 300 and 500 which keep the transformers in separate boxes (hence the brain and brawn type rack arrangements in the multibox systems) but for the 250 / 200 it's best to separate them if you can for best performance. As Simon mentions above, giving the preamp a bit of space always works well.

282 on top, NDX next works better for me, too. Also, I'm surprised to see that he put the Stageline low down amongst the 'brawn' boxes. That seems wrong to me?? Maybe he ran out of space and just put it wherever there was a spare gap.

Regarding the NAPSC, I have mine on the floor, distant from the rack, but that's because I don't want to add another shelf for it, so hiding it on the floor kind of makes sense. I can't see why it should be so important from a SQ point of view though, surely a small PSU like that is less harmful than the bigger PSUs that are on the rack. 

Simon, when I was running a napsc I found it best to keep it as far away as possible.

No problems with that now though

Sounds familiar, if I recall something to do separating the digital control signals from the analog signals. 

Furthermore, the thread also suggested isolating the interconnects that handled the digital signals from those which dealt with the analog signals.

Hence, attention was focused on the positioning of the HCDR, and the Power Supply for the digital Control Center!

Now, did I compare?

Of course not, I just took the Advice of the Forum.

What did I take away from the Thread, Pre Amp on Top, Bronze Stack to the Right of Brains Stack, larger transformers lower shelving, and Napsc maximum separation.

Not to mention Bubble wrap, and exercising the Burndies!

Out!

Allante93!

With a CDX2 in place of your NDX and a 282 I found the system sounded better with the CDX on the top shelf, when I got a 552 it needed to be above the CD player for best sound, absolutely no idea why. I've also found a 250 was better on the lowest shelf.

There are of course plenty of people who disagree so you're going to have to experiment, eventually you can get quite proficiant at swapping boxes on a Fraim without dislodging the glass  or balls but it takes practice.
