Nait 5i issue

[say it as it is]

ok finally got the Nait 5i i had been waiting to get.
nice clean 2008 model he bought it from new
developed a fault where it changes input erratically.
He tried the dealer he bought it from in Glasgow who advised would be £330 plus to get looked at and repaired. He spoke with another repairer he didn't say which one but they more or less told him its the pcb behind the selector buttons failing an be in region of £150 to replace.

so question here anyone else had this fault can it be a diy fix or need to go back to naim or authorised service agent to get parts? if I thought it was cheap enough to do might just bite the bullet get a full service but becomes a very expensive amp then.

anyone dealt with this before still sounds nice so not major concerns about recap etc

Send it to ‘class a’, they are an official naim repair centre & will be less money than the factory.

yes that was my thoughts as well just seeing if this is a common fault or easy fix

My nait5i had a flashing input button and no sound, €350 Later!, naim replaced the "optocoupler"
Thinking back now I should of sold it with the intermittent fault and not given naim another cent for repairing their junk.

If it really is just an optocoupler that had failed, then that’s absolutely criminal, they could’ve done it for 1/10th of that (plus postage obviously).

This my concern that it's something simple but the standard route is replace the pcb at cost.
Any recommendations for someone to look at this who won't charge an arm and a leg

Ouch ! I’ll keep my vintage no fuss no frill Naim amps then !

Just naim standard cost no matter what it's eye watering hence why other companies service and repair at half the cost

Yes, Witch Hat or Class A HIFI repairs.

witch hat quoted the previous owner £150 i think

That seems more reasonable, have you paid a suitably reduced price to take account of that?

Nait 5/NAC 112
Those are the Naim kit to avoid

 

[Woodface]

Naim charge a flat £350, they also have a approved service agent or you can use an independent.

I fail to see the problem really, at least they look after past products.

That’s what my ears told me a few years ago. Didn’t listen to my wallet and got a Supernait instead !

 

[Olsen]

Don't get me wrong
Most of their amplifiers are great IMO
