Cable length

Minimum speaker cable length for a NAP 150 and NAC 112? i am trying to keep my setup alive and have a lead on some 7ft cables? Any advice would be appreciated.
Thanks

Try this FAQ page:

You should use 12ft of naca5. This is early “classic” and potentially 20 years old kit so I would treat it the same as the older olive kit; i.e., follow naim’s recommendations.
