overview
Almost any Hi-Fi component can be upgraded to higher performance using our techniques and components. The two things go together – the know-how and the right component. Over the last 25 plus years, we have developed our knowledge of where the biggest problems lie and how to overcome them to unleash better performance from a given piece of equipment.

Developed in 1993, this hugely popular amplifer from Naim benfits from the following upgrades to both the pre-amp and power amp section. A total of 52 internal component changes plus an upgrade to the binding posts make this a fantastic upgrade. A later version added remote control functionality which was the R model.

A neat upgrade is to include our Balance Control Bypass option. We completely remove the balance control which reduces the number of connections in the audio path, making a clearly audible improvement. The circuit design does call for some resistance to be present otherwise no signal will get through, so we use four extremely high quality resistors to achieve this. An in-house, custom 3D printed cap is then fitted to cover the hole. We do not do this as standard, please request this when you order.


Because of its slim design, there is limited room on the back panel to make major changes such as fitting an IEC socket. To allow you to connect your choice of upgraded power cable, we have created an inline IEC socket wired with a short length of PowerKord.

For the majority of the capacitor changes, we use Russ' favored Panasonic Audio Grade caps. Where possible, we will endeavor to use the superb Kimber Kaps.
Naim updated the 3 to the 3R with the R simply adding Remote Control functionality. The core internals are pretty much the same, so if you have this amp, it is the same cost for the upgrade.

If you don't have exactly the same model as listed above, but a very similar unit, then it's highly likely that the same upgrades will apply. But we can't guarantee that until we have the unit here for inspection.
Equipment upgrades are proving hugely popular. During peak times there may be a wait of several weeks before we can carry out the upgrade. So before we get your equipment here, it must be booked in so we can ensure a speedy turnaround of the upgrade. Once you have placed your order, we will contact you to arrange a suitable week and getting the equipment here.
In Person
For those of you who are local enough or if you fancy a trip to the lakes, you can drop off your equipment personally and then collect it when it’s complete or we can ship it back to you.
By Courier
We can arrange a courier collection of your equipment for an additional cost. We currently use UPS.
To make things easier, we can offer several collection options.
1. We can arrange a specific day for the courier to call and collect your equipment. Someone will need to be available all day at the collection address as we’re unable to arrange a time slot for collections.
2. Dropping off at a UPS Access Point. UPS use a network of local shops to deliver and collect parcels from and to. We can either post you a collection label or email you the label (you will need to print the label at home/work). Securely box up your equipment, affix the collection label to the outside of the box and take it to your preferred Access Point where you will be issued a receipt. UPS Access Points can be found here (link opens in a new window), simply enter you postcode to find your nearest one.

This RA upgrade for the Nait 3 has taken my 3R to 95% of an 82/HiCap/250 set... job done!
5 stars all the way- from emails, shipping- and sonics.
Anyone with an unserviced Nait 3 (or 3R) should go for it!
100% recommend.
Source 1st, always- but still, amazing what you can achieve with a 30wpc amp, and some half-decent speakers.
Suitably impressed with this upgrade package- have sold the 82/250 combo.

Why do we upgrade equipment?
Almost any Hi-Fi component can be upgraded to higher performance using our techniques and components. The two things go together – the know-how and the right component.

Naim Nait 3 Integrated Amp Upgrade

Developed in 1993, this hugely popular amplifer from Naim benfits from the following upgrades to both the pre-amp and power amp section. A total of 52 internal component changes plus an upgrade to the binding posts make this a fantastic upgrade. A later version added remote control functionality which was the R model.
Pre-amp and Power amplifier section
35 capacitor upgrades including Kimber Kap capacitors. We use Russ's favoured audio grade Panasonic caps which give a smooth and detailed sound where it's not possible to use Kimber.

Balance Control Bypass
A neat upgrade is to include our Balance Control Bypass option. We completely remove the balance control which reduces the number of connections in the audio path, making a clearly audible improvement. The circuit design does call for some resistance to be present otherwise no signal will get through, so we use four extremely high quality resistors to achieve this. An in-house, custom 3D printed cap is then fitted to cover the hole. We do not do this as standard, please request this when you order.

Binding posts
We fit our high performance, nickel plated binding posts which allows the connection of speaker cable terminated with bare wire, 4mm bananas or 6mm spades.

IEC Connection
Because of its slim design, there is limited room on the back panel to make major changes such as fitting an IEC socket. To allow you to connect your choice of upgraded power cable, we have created an inline IEC socket wired with a short length of PowerKord.

Capacitors
For the majority of the capacitor changes, we use Russ' favored Panasonic Audio Grade caps. Where possible, we will endeavor to use the superb Kimber Kaps.
Naim Nait 3R
Naim updated the 3 to the 3R with the R simply adding Remote Control functionality. The core internals are pretty much the same, so if you have this amp, it is the same cost for the upgrade.

Different Model?
If you don't have exactly the same model as listed above, but a very similar unit, then it's highly likely that the same upgrades will apply. But we can't guarantee that until we have the unit here for inspection.

It’s important to note that this service is specifically aimed at upgrading equipment in good working condition rather than repairing or servicing. Why? Well, these are two very different processes. Our upgrades look at improving existing parts – like capacitors, for example – and we have an awful lot of knowledge and experience of doing this. As many of these parts do wear over time, replacing them can have the added benefit of actually making the equipment more reliable and longer-lasting, but that is an added bonus rather than the central aim, which is to improve performance.
When it comes to servicing and repair, however, the specific knowledge of individual pieces of equipment that is required, along with access to the original electronic schematics, makes it unwise for anyone other than the manufacturer or authorised service agent to carry out this type of work.
The upgrade comes with a 2 year warranty, including all parts that we've used. This excludes failure of components beyond the work we have carried out. We therefore ask that the equipment you send for upgrade is in good working order.
Please note this is just an upgrade modification, it does not include the Naim Nait 3.
