When it comes to cables, I'm not a believer..... so its plain 6 mm2 installation wire to the speakers. Signal cables are from the time I actually did believe, so they are teflon-insulated silver stuff. Balanced of course.....

I agree - the thing with the nCores is that you want to make sure the cable has a low enough resistance and can carry enough current - you don't want to waste the capabilities of the nCore on the cable instead of the speaker.

As I am multiamping, I am using a 4 x 4mm from Van Damme.

Sam,
I've put in the two way ATCs on standard Sound Anchors stands before, they are very solid and sturdy. No need for the custom built ones. fill the bodies with sand if you must. But get the standard adjustable studio model, then you can fit it to your room in situ. Its a very nice sounding system. Even better I bet when powered by the Ncore. I was using Bryston 4B SST's on them.

coupling beneath the speaker and using spikes are good ideas, but that will get you 99% or more without committing yourself to one position.

wire? big and short. I, like Stig (or Julf), don't believe in wire, (isn't this the wireless age?) Even though I can sometimes hear a difference between different juju wires, I attribute it to mucking up something, at least for speakers. If a speaker/amp combination relys on a certain wire with non standard specifications to sound good, its broken.

I received my amps ((4) nc400 and (2) smps600 for biamping) and am now thinking about enclosures.
I read someone here (was it Sam Lord?) saying that steel panels should be avoided, or at least cable runs should be isolated from them.

Cheap enclosuresd are typically made with aluminium fronts and steel panels:
Boitiers économiques - Audiophonics - Câbles, Amplificateurs et Accessoires DIY

Should these be avoided in favor of all-aluminium ones?

I would like the cheapest enclosure I can get as I don't care for design and it is meant to be stuck on the rear of a wooden box anyway (à la plate amp)

Can't remember anything about steel panels - curious about what the reason would be. OK, different metals have differing abilities to isolate magnetic fields, but to me it sounds like a bit of typical audiophile superstition.

isolate magnetic fields

What I remember from my time at the HTS (B.sc EE for non Dutch members) is that you need a ferro metal for that. Not sure why or how it would affect the sound quality of a N core amp??? I would guestimate it doesn't matter at all...

I agree - but my EE studies (Helsinki University of Technology) were 30 years ago, and my memory isn't what it never was. Anyway, pretty sure a box of mu-metal would be pretty expensive...

The general claim for using alu cases for audio equipment is due to that it is supposed to be non-magnetic and thereby shouldn´t add any induction to circuitry and cables inside and around it. Other good qualities are far better heat conduction than steel and good mechanical stability. The later is typically due to far greater plate thickness too.

Whether any of these apply for the ncore is of course a different matter.

The ncore amp that I have heard was in a thin steel case (if I got it correctly) and I did notice that the case got more than luke warm. So if ncores generally waste a lot of heat when idling heat conduction could be a practical concern...

That said, the amp was powered by a smps600 so that might very well have been the actual cause for the heat dissipation to the case.

Any other experiences with heat dissipation from ncore and/or smps600 out there?
