Yes, not a technique I used but I can see the logic in it. The other option some use is DSP, using the low level connection with electronics that don’t affect the main speakers. Again I never used it myself but it’s an option if manual configuration doesn’t produce geed results.

When it comes to subwoofers, it’s a subject discussed on forums where a lot of people regard it as an item that gets chucked into the system as the last choice and with ‘any old cable will do’. Also, it’s rare to hear of anyone spending the kind of money on them and cables, as they do on the other components, so getting varied opinions is difficult. Subwoofers are very complex things, expensive to make and pretty hard to set up properly.
The subwoofer cable 100% makes a difference. Poor cable smears the signal. Those very subtle, tight driver movements get blurred.
Power supply, Power-Line on the sub, Synergistic Pink fuse in the mains plug, cable and connectors all add up to a difference.

Thanks. I’ve measured my cable and it has 100 ohm resistance, so it’s been built properly. I’ll be having a play with getting the sub set up and running later this week, which should be an entertaining evening
You can’t put a Powerline on an N-Sub, it won’t fit.
N-Sub ground loop? Loud buzz after high-level connection!
So, while waiting for my Leyline cable to arrive, I temporarily hooked up some cheap speaker wire I had lying around.
I connected the N-Sub using the high-level input. The bell wire is screwed to the speaker binding posts, and the Naim plugs are connected to the rear of the same binding posts, with polarity checked throughout.
After connecting the mains and powering everything up, I had a really loud hum/buzz!
So I immediately turned n-sub off. to me it sounds like some kind of ground loop issue… but I´m not really qualified to tell. checked the n-sub and grund switch is set to internal.
One thing that may be relevant is that the N-Sub is plugged into a different power strip from the rest of the system, as it’s positioned some distance away.
Has anyone experienced something similar, or have any suggestions on how to troubleshoot this?
Connected the N-Sub to the same mains supply as the rest of the system and the buzzing disappeared completely. Looks like it was a grounding issue after all.
Now I just need to find a suitable extension lead, as the N-Sub is a bit too far from the power strip…
Read through the manual and perhaps the way to go is to switch the earth to external and run a simple wire between the N-Sub and NAC 202 ground post?
Would this work and give the same result? I’d really like to avoid having a 10m+ mains cable across the floor.
Had/have similar events with my nsub.
You’re doing all the right things/suggestions. They’re the things I would be trying.

Thanks a lot, good to know!

Temporary setup, trying some different positions for the n-sub. Getting used to the new speaker and the settings, not really sure what to listen for and a bit of a hassle to move the n-sub around so not really easy to get it right.
House renovation not finished, curtains carpets and bookshelfs on the sidewalls shall hopefully help some with reflections and perhaps damping…
