Musical Fidelity A308cr Power Amp Upgrade

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.


Rated at 250Wpc into 8 ohms, Musical Fidelitys A308 power amplifier is a true dual-mono design, with separate torroidal transformers for each channel, choke regulation, and 40,000 microfarads of filter capacitance in the power supply. The audio circuit is all discrete, and the output stage comprises three pairs of bipolar output devices per channel.




This 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 signal wiring is taking care of using Kimber cable. For the power, we’ve used TCX copper (a thicker, single strand version of what we use in our PowerKord’s. Over 1.5m is used from input to the transformers





For the signal wire, we've used a combination of the thicker Kimber TCX for high current signals (connections to the binding post) and just under a metre of a thinner gauge, pure copper Kimber TCSS for all other connections


24 significant component upgrades/changes are made across the power supply and analogue circuitry including inputs and outputs. Upgrades include Russ's favoured audio grade Panasonic capacitors which give a smooth and detailed sound and 8 large, 10,000uf reservoir caps. The unit is completely disassembled to gain access to key areas of upgrade.





For the majority of the capacitor changes, we use Russ's favoured Panasonic Audio Grade caps. Where possible, we will endeavour to use the superb Kimber Kaps as shown here. Post upgrade, the unit is then soak tested for 24 hours.





We upgrade your preferred RCA input sockets with nextgen WBT-0210 Cu sockets.





The primary binding posts are upgraded to WBT-0708 Cu Speaker posts.




To clean up and give the power supply an upgrade of SuperFuses™ are fitted throughout, a Silencer™ mains filter is fitted to the mains input (internally). A full re-wire with Kimber pure copper TCX from mains input to transformer.






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.




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.
