One channel

Have you checked the SNAIC4 cable between 272 and 200 is ok ?

Is this on all inputs ?

I haven’t checked the snaic cable yet, is it common for them to get damaged and only work through one channel?

its the same with all inputs on the 272 

It's not common, but it's a possibility, particularly if the plug has been pulled out by the cable end a few too many times.

Are you getting any hiss/white noise of any level from the non-working channel?

Yes there’s some hissing/white noise from the channel that isn’t working. Does this mean it’s more likely a cable problem? I’ve ordered a replacement snaic cable

im going to be very disappointed if I have to start posting boxes off to be repaired!

Take it this wasn't purchased from a shop or dealer then

Otherwise it's straight back to them ...

I bought the naim 200 over 30 days ago, and the naim 272 a couple of weeks ago both on eBay. Surely they wouldn’t qualify for a return now?

The hiss/white noise from the non-working channel is quite possibly good news - it means it's not totally dead. Check the SNAIC*.

n.b. make sure whenever plugging in or unplugging a SNAIC that the equipment is powered off - horrible noises (and possibly damaged drivers) otherwise!

In addition to all of the above, have you got some headphones you can plug into the 272 (do both channels work now through the headphones ?) which may help start to pin point the problem area.

From what you say though, a faulty SNAIC4 seems very likely.

I'm not sure what the law allows for distance-buying, in some cases I've heard buyers have more protection than if they bought from a shop, ironically. 

Here's what you may be able to do based on how I've handled things in a similar situation. First step is to call your credit card provider, explain the scenario (that you both these items on such and such a date and they failed on such and such a date) and see if you are eligible for a dispute case to be opened. In that situation, they will refund you the money, the merchant company which handled the transaction with your seller will then be notified the money has been refunded and they will launch an investigation.

Whether they do or they don't, your next call is to PayPal (if you paid via them) to find out what your rights are under their user policy.

Lastly, it's the people you bought from. Contact them passing on any knowledge gained from steps 1 and 2 asking they either give a refund to cover the cost of repair or take the goods back for full credit. If steps 1 and 2 are no good, then you can still ask anyway, the sellers may be decent folk. If not, go through eBay's dispute service - it might get a result.

Whether your sellers agree to pay for servicing or not, you'll need to contact someone reputable for the work to be done. That's obviously Naim themselves but a cheaper option is Class A in Sheffield who are authorised Naim repairers. You've probably little option as if they are faulty you won't be able to sell them on anyway.

Good luck, hope this helps!

Thank you Richard, James & Jonners,

fingers crossed it fixes it! It sounds like a right kerfuffle returning.

ill report back later this week

I don’t have headphones yet, they’re on the list. It’s pretty expensive starting off from scratch with naim

That seems to me like a very litigious approach. To my mind, the seller should be the first person you contact, not the last. Many ebay sellers are honest and helpful, despite it’s reputation (although sometimes less so after you have left feedback) and many HiFi enthusiasts likewise. Give them a chance to help before throwing the book at them.

Agreed ChrisSU, I had made an assumption that if these products were received as faulty by W12 then the seller would have known as such before listing them for sale which in my mind would be devious. That's why I would do my homework to find out what my rights are before contacting them. 

The first thing to do is to establish which unit is faulty. It is very unlikely to be both and so pointless doing anything until that is clear.

Putting a new SNAIC in will only confirm that the problem is or isn’t being caused by the SNAIC.

In the absence of other ways of finding out where the problem is, I would buy a cheap interconnect that had two RCA plugs at the 272 end instead of a DIN and the DIN or whatever it is at the 200 end. Then you can swap the RCA plugs over and see whether the problem stays on the same channel or not. I think you have to enable the RCA outputs in the 272 setup to do that, but that takes just a few seconds.

If the fault stays on the same channel then the 200 is faulty and if the fault moves to the other channel then the 272 is faulty. It’s also worth making sure that the 272 is getting a signal on both channels at the input, but of course if you are using upnp or Tidal for example then you can assume that the input to both channels will be there.

As already suggested plugging headphones (even ear buds with a cheap adapter) into the 272 headphone socket can confirm that there is a problem in the 272, but the fact they work doesn’t confirm that there is no problem in the 272.

It’s all logical stuff anyway.

Yes of course, I’ve been turning off everything at the mains before unplugging or plugging anything at all.

The above advice is all good stuff for fault finding

It should be fairly easy to work out which one is not working

Where they ok when you got them or is this the first trial ?

Morning all, the new snaic cable did the trick- I’m now listening to incredible audio. So happy and grateful for help, I’d never have guessed it could be a cable.

just waiting for the Allae’s to arrive now! 

That's excellent news!  

Good news - just in time for the weekend too

Sometimes it's the simplest things! I had a "1 channel" issue I posted on a couple of weeks ago, seemed to cure itself but came back again this week. It turned out to be cables as well. The connections on the back of the 282 are fairly close together and if most of them are occupied it's quite tricky to get the collars "locked in" properly when you've a touch of arthritis as I have. After wearing some surgical gloves to aid purchase I was able to get the collars locked in properly.
