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.

Audiolab 6000 CDT Upgrade

The 6000CDT is a dedicated CD transport incorporating the same slot-loading mechanism as audiolab’s flagship CD player, the 8300 model. By mounting the transport mechanism in its own, electromagnetically shielded enclosure, and including a dedicated power supply, the digital signal extraction from any CD is said to be as accurate and precise as it is possible to achieve. So, a great foundation on which to upgrade!

We were extremely happy with this upgrade. In stock form the 6000DCT is a really good transport. When upgraded we heard more detail, musicality, bass and dynamics….lovely…

Component Upgrades

As you can see, being just a transport it's pretty empty inside. But, 25 significant component upgrades/changes are made across the power supply and digital audio circuit. Post upgrade, the unit is then soak tested for 24 hours.

The left shows the 6000CDT pre upgrade. On the right, post upgrade.

Upgrades primarily include Russ's favoured audio grade Panasonic capacitors which give a smooth and detailed sound. Where possible, we will endeavor to use the superb Kimber Kaps.

Master Clock

A major source of improved sound quality is made by upgrading the original master clock. The clock is in charge of the distribution and timing of the digital audio data. The greater the accuracy of the clock then the lower the jitter (digital distortion) is.

On the left is the upgraded Trichord Master clock we use. On the right is a typical clock that's removed. Quite a difference!


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

We would normally change the IEC socket to one of our own, but on this model the customer supplied there own Furutech socket and asked us to fit that which you can see in the above picture.


Any applicable internal wiring has been taken care of with Kimber pure copper TCX wire.

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
