There's nothing about this on Naim's site. There is a long speil about upgrading which makes a claim about fantastic residuals which must surely be out of date by now, going off the mountains of used kit in dealers, ebay and elsewhere.
On the boxes of my 500 series kit, it said 'world class hi-fi'. The problem is that there is a lot of genuine world class hi-fi out there which does not require 'correct set up.'
Does 'correct set-up' mean buying hi-lines, Power lines and Fraim, because on a £70k rig I think Naim's site should make very clear this extra spending is required.
Anyway, in my view the top stuff fails to work and by the time you get to the top of the pyramid (repeat pyramid) you find the dealer and Salisbury are long gone - unless you'd like to buy a cheapo £2k dac or some PowerLines, of course.
Blaming poor set up is the last refuge, in my hi-fi experience.
Anyway, don't apply for PR job at Salisbury, will you?
