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.

Oppo BDP-203 Upgrade

Launched late 2016, the OPPO-203 was the lighter (in weight and specification!) to the 205, but it still packs quite a punch when it comes to picture and sound. OPPO have really built a reputation for going that extra mile with build quality and functionality. The 203 was the first and last (with the exception of the 205) proper UHD player from the company.

Pretty much like all OPPO's before, the BDP-203EU focuses largely on HDMI transmission. An interesting feature is its HDMI input: it’s possible to send HDMI video into the OPPO 203 and use it as a sort of “lite” video processing device without ever inserting a single disc into it. An incredibly useful feature is its two HDMI outputs. You can send video straight to your TV and then audio independently to your AV receiver. OPPO have worked with Mediatek to produce an updated, dual-core chip which is responsible for core video decoding, de-interlacing, scaling, and network interfacing, there's also a second Marvell chip for additional noise reduction.

The OPPO BDP-203 is a great disc spinner (it's our default in-house player here at Russ Andrews HQ) but we've identified quite a few key areas for upgrade. The OPPO BDP-203 upgrade build on the strengths of the player, especially the power supplies and clock. Everything you love about the sound and picture remains – it just gets so much better.

Component Upgrades

56 component upgrades/changes are made across the power supply, audio board and video board. Upgrades include Russ's favored audio grade Panasonic capacitors which give a smooth and detailed sound and of course that hugely important Master Clock upgrade which improves jitter (timing) performance.

Your 203 is completely disassembled to gain access to key areas of upgrade. Post upgrade, the unit is then soak tested for 24 hours.


Starting with the mains input, we change the IEC socket to our upgraded version which features our proprietary Super Burn-in process and wired with Kimber TCX pure copper wiring. A Silencer™ mains filter is then fitted to clean the electricity supply prior to the power supply board. Further mains conditioning is added by the inclusion of the ClarityMains™ module . The power supply section is then upgraded with Panasonic Audiograde Caps.


Inside the OPPO 203 is a Master Clock controlling all aspects of the digital domain. We remove this clock (which is about the size of a pin head) and replace it with an extremely high accuracy (+/- 5ppm) Clock 4, wired to the board with Kimber cable. The entire design of the component, is of course important, but if the quality of the clock is not up to scratch then the overall performance will suffer. We substitute the standard clock in OPPO 203 with a Trichord low jitter. ‘Clock 4’ oscillator which in our professional opinion greatly enhances sound and picture quality of the 203.

Different Model?

If you don't have exactly the OPPO 203, but perhaps a 103 or 205, then we also offer an upgrade for those players too! 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 your 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 an upgrade modification, it does not include an OPPO 203 Blu-ray player.
