We are one of only three service centres in the UK authorised by Naim to repair and service their products.
To maintain optimum sonic performance it is recommended that Naim equipment is serviced every 8-10 years for power amps and power supplies, 10-12 years for pre-amps. Below is a rough guide to actual costs assuming goods are in working order.
All units are kept to Naim specification, we do not modify units by fitting inferior specification or so called equivalent parts.
Our spares are sourced direct from Naim.
If booked in advance, most units can be serviced whilst you wait.
Please note, if you are not local to Sheffield we can arrange collection and delivery from £16.00 per box fully insured each way with a national courier, this price is for UK mainland only.
If sending any item to us then please ensure the packaging is sufficient or the courier will not be responsible for any damage caused.
Any item received that is poorly packaged will incur extra cost for return shipping.
See serial numbers at the end of the page to obtain the year your equipment was manufactured.
This is just a sample of the equipment we service.
All prices are inclusive.
This assumes the regular service work but nothing unusual such as dead transformers or output stage failure.
Please ask about prices for other Naim equipment.
Parts and labour are guaranteed for 12 months.
Naim and their authorised service departments will service and repair units to
100% Naim specification, as all spares are carefully selected at Naim.
We are proud to be an authorised service department.
Always ask who carried out the service work and get a detailed list of all parts fitted and work carried out.
If in any doubt ask for internal pictures, send them to me and I can check if the correct parts are fitted.
If it says Naim on the outside you want it to be Naim on the inside...
Why Should I have my old equipment serviced ?
Below are recent quotes from a happy customers
Nac-42 / Nap-110
A few weeks ago, I had my 23 year old 42/110 serviced (and upgraded to a 42/140) by Class-A in Sheffield. The customer service was excellent, the cost was very reasonable and the music just keeps getting better as the units burn-in. I can only commend Naim for their commitment to long term service/product support, and Class-A for their first-rate execution of the work. Anyone considering getting their older kit serviced/upgraded should not hesitate if funds allow - the benefits are remarkable.
Thanks for the prompt work on Saturday. Plugged them in as soon as I got home and God, what a difference. A proper soundstage, superb clarity and details I'd never heard before and most importantly proper bass. As I mentioned in the shop, I'd struggled for ages getting any and getting the bass to sound like it was coming from the speakers. It seemed to emanate somewhere above them and I'd just put it down to weird room acoustics. I guess basically after 21 years untreated, the amps had run out of steam. I've noticed also that the pre-amp doesn't need the volume to be so high to get the same levels as before.
Hi Darran, I meant to email you, but have had my hands full with all sorts of non-hi-fi stuff. I want to thank you for the good service, swift work, and most of all with the benefit the recap brought. I am listening to it now as my son and wife sleeps. What hits me is that my 202,200, Hi-Cap, Napsc, CDX-2, Hi-line, Allaes (all Naim ; )) sounds much more natural and easy to listen to than before, compared to the non-recapped system and without any Hi-Cap at all. The detail-level has increased, as well as dynamics and PRaT. The music just flows, and the system now makes me want to listen to more and more records, which matters the most in this hobby. Thank you!
Nac-112 / Nap-150
Received the NAC112 and NAP150 back from Class A in Sheffield. The difference is amazing. I hadn't realised how much the sound had deteriorated over the last 13 years! Very pleased with the works Darran has carried out.
Nap 135 / Nap 250 fascias now in stock

When is a cd not a cd ?
When it is "copy protected" You may have read in the press about major record companies releasing cd's with copy protection systems that means the discs will refuse to play properly on some players. Well it's true. crazy but true. These cd's which incidentally fall outside the "Red Book" cd specification laid down by Sony and Philips will occasionally misbehave on Naim and many other cd players. However we can offer a fix. Thanks to being one of the few independent cd manufacturers to write it's own cd control software Naim can offer a player software update for CDS2, CDX2, CDS, CD5 and CD3.5 that will cure the problem. So if you are afflicted with a copy protected cd that you just cannot live without call us now on 0114-2588400 to arrange a solution. Cost is £35.00 and work can be carried out whilst you wait if you call in advance to arrange an appointment.
CD's skipping during play ?
First thing to check is the state of the puck. The rubber contacts do wear with age and allow the cd to be clamped less tightly. It is recommended you do not leave a cd inside the player with puck in place for long periods of time as this can cause premature wear. We always have stock of new pucks and can mail order them, please ask for costs. Only genuine Naim parts supplied.
We are unable to supply any internal spare parts for Naim equipment.
