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-103 Upgrade

Launched late 2012, the OPPO-103 was the lighter (in weight and specification!) to the 105, 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 qualuty and functionality. The 103 for example was one of the first Blu-ray player to upscale to 4K.

The BDP-103EU focuses largely on HDMI transmission i.e. picture performance as an interesting feature is its HDMI input: it’s possible to send HDMI video into the OPPO 103 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 spec'd the impressive dual-core Mediatek 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-103 is a great disc spinner but we've identified some key areas ripe for upgrade. The OPPO BDP-103 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

60 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.

The 103 is completely disassembled to gain access to key areas of upgrade. Post upgrade, the unit is then soak tested for 24 hours.


Firstly the inbuilt IEC filter, based on chokes with high saturation resistance is removed and replaced with our Silencer™ mains filter. The connection from the mains input to the power supply is upgraded with Kimber TCX pure copper wiring. The power supply section is then upgraded with Panasonic Audiograde Caps.


Inside the OPPO 103 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 103 with our low jitter. ‘Clock 4’ oscillator which in our professional opinion greatly enhances sound and picture quality of the 103.

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 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 the Oppo player.

"Transforms The Image And Sound, Amazing"
This is quite an amazing upgrade. Starting with the sound using HDMI and Coax there is a lot more detail and one of the biggest changes in the scale of the sound. Bass is more solid, the ambience of the sounds and that ‘cinema sound’ you get in the big auditoriums is brought right into your home.

On DVD concerts I have had for years I am hearing a level of detail that has never been there before, I have had Sony S5000ES blu-ray player and that didn’t get anywhere near the Oppo upgraded sound.

The picture is far sharper with a lot more detail, colours jump off the screen, but very natural. It looks photo realistic on my calibrated OLED TV.

Brilliant and well worth the money!
