@chayro - here’s a link from the NAIM community forum

So the lack of Inductance in the outtput stage of NAIM amps requires a certain inductance to be present in the cables for the amp to perform correctly, but the high capacitance can destroy amps
Having exchanged emails wil NAIM support when I first got my 5i MKII amp - they stated categorically it is the capacitance element that drives an amp into oscilation not the inductance. But for best sound, cables with similar ratings to the NACA5 cables should be used
Here’s a link to a similar thread in another forum

Here’s what QED has to say about it...
https://www.qed.co.uk/qed-genesis-report#capacitance_versus_inductance
On the practical side - A friend actually did destroy both his Ayre and Gryphon amps (both high current designs) using high capacitance speaker cables. Once he got them repaired he changed his cables and now all is well
The interesting thing about this particular topic of conversation is...
- the amp companies know about this issue
- the speaker cable companies know about this issue
- very few technicians seem to know about this issue
- retail outlets know NOTHING of this issue
- AND no one warns the consumer about it
There used to be a page on the NAIM web site warning about this issue, but it appears to have been removed..
PLEASE NOTE - it is ONLY high current SOLID STATE designs that have any type of issue with High Capacitance speaker cables
Tube amps are just fine - i.e. to my current level of knowledge

Another factor to be considered with speaker cables is amplifier stability. In some cases, a little extra capacitance at the output can make an amplifier oscillate, overheat and even self-destruct. Or it may oscillate momentarily at high radio frequencies during operation and show no obvious symptoms.From their web site:
