overview
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. Over the last 30 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.

Our upgrades build on the strengths of the component. Everything you love about the sound remains – it just gets so much better.

Naim CD5si

Launched way back in 2012, the CD5si was an upgrade over the entry level CD5s in Naim Audio’s portfolio of CD players.





A step forward in performance from the CD5i featuring several improvements to key areas. An upgraded Burr Brown PCM 1793 DAC, a higher precision clock supporting the new DAC helping to reduce jitter and improved transport mechanism mounted in Naim Audio’s unique improved swing drawer.





We were extremely happy with this upgrade. In stock form the CD5si is a really good player. When upgraded we heard more detail, musicality, bass and dynamics….lovely…

Component Upgrades

87 significant component upgrades/changes are made across the power supply and audio circuits. Upgrades primarily include Russ's favoured audio grade Panasonic capacitors which give a smooth and detailed sound. Where possible, we will endeavour to use the superb Kimber Kaps. Post upgrade, the unit is then soak tested for 24 hours.

Power

The unit is completely disassembled to gain access to key areas of upgrade.



The CD5si power supply is based around an uncomplicated but ‘very’ high quality toroidal psu, so there are minimal upgrades required in this area. However to clean up the incoming power, a Silencer™ mains filter and internal SuperFuse™ are fitted.





Finally an external Ground Terminal is fitted to enable easy integration with our grounding solution.




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 or similar upgrades will apply. But we can't guarantee that until we have the unit here for inspection. Get in touch and let us know what you have.





How the service works

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.


Exclamation IconEquipment condition.
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 CD5si CD Player
