Considering moving away from my Supernait 1

Or 82 Hicap 250. Will sound better than SN3 or 202 200. Equivalent of 282 Hicap 250 at bargain price. £2500 for the three. I think widening horizons and look at what you can do with vintage Naim pays dividends.

And with a service they will sound amazing.

Pretty much what I have done and have built my system with a mix of old and new. All working in cymbiosis!

Just checking… shouldn’t that be connected to the shell (outer) of the rca?

I personally connected it to the centre and it worked fine.

Edit… just checked the cable and it was the centre pin I soldered to the flex.

which I think I now own!

Excellent… I loved that DAC… if it is the same one… it’s what started me on the TT2/Mscaler journey. I wanted to keep it and use it with the TV but the better half wasn’t up for a large pair of speakers in the living room!

Hope you’re enjoying it as much as I did!

Edit… just checked the sales info and it’s a different name so might not be mine after all.

If it kills the hum fine, but I think the idea is to connect signal ground to mains ground in one place only as per Naim’s design.

This thread may be relevant…

I’d suggest you should leave the live and neutral pins in the plug too, just not connected. If you don’t, it’s possible to put the plug in upside down, which will open the safety shutters in the socket and expose the live contacts.

Yes, stopped it straight away. I was using optical at the time… if I remember correctly, I first made up the cable for when I had a Bluesound Node 2 which did the same thing.

I assume an iFi Audio GroundHog+ will do exactly what you are suggesting?

I have one other source connected, Rega PR6 via Stageline. The RP6 doesn’t use a ground cable, I believe it is done via RCA.

I’ve not read the whole thread, but SN1 owner here (driving S600s). The removal of the DAC means that a simple update is not possible. I’ve had mine 12+ years. Not interested in vinyl, but using a couple of digital inputs. SN4 to have a DAC? Yes please. Absolutely and utterly uninterested in the laughably-named UPnP world of twonky streaming (“universal”? “plug-and-play”? Spare me.).

It looks like it should… in a lot more professional way than I described :joy: If you can pick one up through a 14-30 free returns that would be good… just in case.

A wire connecting the grounding pins should be sufficient and take the hum away.

I like din connections for the automatically included grounding :slight_smile:

But hey, I’m a Naim convert …

And Chord support and promptly answered my question and suggested one of these. image

Looks promising, I’d imagine a lot cheaper as well. I’ve only had to contact Chord Support once but they were really good. Did they say how its connected etc. Just for reference for anyone else who finds this thread and has the same problem… I’ve seen it come up a few times and this looks like an easy and cost effective solution.

As per Chord’s message.

If the Naim has a ground lift switch this should be moved to the other position. If this has no effect, you will need something like THIS to go from an unused input on the Qutest to the ground of the Naim.

Yes they responded very quickly! I emailed Naim at the same time, let’s see their solution.

Surely just connect to the turntable signal ground connection on the ‘nait? I wouldn’t bring a mains plug into the equation.

This is how I have my Qutest grounded. My power supply for the Qutest, Allo Shanti, has an external ground connection. A ground wire from there to the Supernait 2 ground post, hum eliminated.

BNC to ground added, hum gone!

Excellent… if you can, it’s still worth using a Power bank for powering it as it does help lower the noise floor. Just use a micro usb extension cable plugged into the Qutest and run it to a point of easy access and then plug the power bank into the extension.

As well as making it easy to access, it also saves plugging and unplugging the power bank into the Qutest which would wear the contacts over time. The Anker 20100 used to last me abut 12-14hrs or so playtime.

One better put the battery on a timer switch!

Certainly if that’s an option… If the plug on the back of the Qutest is going to be unplugged often though, it’s still a good idea to pop in a small extension as micro usb sockets have a habit of wearing out. It’s a lot easier to replace a £1 cable than replacing the socket on the circuit board.

Anyway… enjoy, the Qutest is a little powerhouse of a DAC for something so small it seems almost impossible!
