Acrylic : Does it block electromagnetic interaction between boxes?

Posted by: kevin J Carden on 07 March 2017

Quote from the blurb for Statement Amps on Naim Website:

"The NAC S1 and NAP S1 share the same fundamental layout. The noisy power supply is housed in the base and sensitive electronics are nestled above. Each section is divided by an acrylic centre-piece that blocks interaction. "

I'm not certain that this refers to power supply fields and their effects on signal electronics, but assume that's what is meant (?)

if so, I'm wondering if we should we all be placing acrylic shelves or partitions between our brain and brawn stacks?

Not quite Kevin - it's just used in the Statement enclosure to form a break in the metal case work to stop eddy currents induced into the lower section case by the transformer circulating around the whole of the enclosure (as would be the case if it was continuous metal) allowing a 'quieter' environment in the top section for the sensitive pre-amp electronics.

Thanks James. Understood ( at least after a quick trawl of internet to refresh my memory on eddy currents and their effects on aluminium !) . Of course it now makes sense to me that the acrylic is essentially shaped like a gasket and only seperates the casework, allowing the wired componentry to pass through the middle - otherwise how else would that happen! Doh!
