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.

Musical Fidelity M6si Amp Upgrade





Launched in 2014 as there all new, top of the range ‘M’ series integrated amplifier, the M6si is configured as two independent monobloc power amps with a separate pre amp delivering 220 watts per channel. With a wealth of inputs including a MM and MC Phono stage, USB DAC up to 24bit 96kHz asynchronous and phono and XLR line level inputs, it’s a real power house… just read the reviews!




Russ has been a long-time fan of Musical Fidelity and we use its smaller the brother, the M3si in our demo system. The design provides a great platform to upgrade! Our upgrades build on the strengths of the amplifier. Everything you love about the sound remains – it just gets so much better.

Internal wiring

Internal signal wiring is taking care of, using a combination of Kimber pure copper wire. For the power, we’ve used TCX (a thicker, single wire cable that we use in our PowerKord’s) to connect from the power input section to the transformer and from the power amp to the speaker output.





For the signal wire, we've used Kimber PBJ, tr-braid and single strand TCSS. If you would prefer silver in place of the copper wiring, then lket us know. Contact us for details.






Component Upgrades

For the majority of the capacitor changes, we use Russ's favoured Panasonic Audio Grade caps. Where possible, we’ve used the superb Kimber Kaps.

25 component upgrades/changes are made across the power supply, pre-amp and power amp and system control PCB. One of the key upgrades is the changing out the 8 large, black capacitors situated in the power amplifier section. The amplifier is completely disassembled to gain access to key areas of upgrade.





Power

To clean up and give the power supply an upgrade SuperFuses™ (optional – see Level 2) and Silencer™ mains filter are fitted.



Connections

While it's a cracking amp, we felt the binding posts weren't so good and opted for the excellent WBT-0710 copper version which deliver a rock solid connecting between amp and cable.




Level 1 or Level 2?

Level 1 is everything above. Level 2 adds four, internal SuperFuses and a full upgrade to the separate Phono Stage section. SuperFuses can be added at any point in the future and if you don't use the Phono stage, then obviously there's no advantage in having it done. Which is why these are an option.

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 Musical Fidelity amplifier.
