Technical issues to use NacA5

don't you like the Holy Grail ?

You can use another cable. If it is marginal electrically and your speakers have particular characteristics then you can blow your amp up.

Essentially if your cable is low inductance and your speakers are high capacitance you may have a problem. No one here can say 'safe' or 'unsafe'.

It probably boils down to 'if you have to ask the question you should probably follow the Naim recommendation of greater than 3.5m NACA speaker cable per channel'

Naim sent me a e mail "The reason you need to use A5 with Naim amp´s is because we don´t use output inductor in amp output stage."
What it means?That A5 has some characteristic that other´s don´t?which is...?

Yes they do, (and few others too).
NACA5 cable are of the low capacity/"high" inductance type. Most others (twisted one particularly) are low inductance/high capacity.
Amplifiers need a filter at their output to avoid high freq to feed the speakers and to ease stability of the amp. Most manufacturers use a coil/resistance at their amp output. Not Naim, instead they use the speaker cable's inductance to do the filter/stabilizer job.

Others end with: added inductor + cable's high capacity= high inductance/high capacitance = difficult load for the amp whatever the speaker is.

Naim= moderate inductance + low capacitance = easier load for the amp, less bad things between amp and speakers = better sound.
