Meridian M2 Speakers-Upgrade

Hi, I have a pair of Meridian M2 active speakers I have owned since new in 1983 which I wish to upgrade. The original tweeters have been replaced with a new / secondhand pair of Kef speakers.
I had intended to remove the amps from the back of the speakers to send them to the U.K Meridian Repair Shop however sadly they have just closed.
I will now have to find a local technician and explain what is required.

As the amps are now over 30 years old I am sure the caps could be upgraded but will need advice on this. I have also heard of wiring upgrades such as running separate power cords to each of the amps (two amps per speakers)

Any advice on upgrading the M2's would be appreciated

Cheers

Phil

I started typing that I do this and have rebuilt and upgraded M2's for other customers..... and then noticed your location!

Any advice would be good :)

Hello Phil. Does your comment mean that Meridian no longer service vintage gear or ... that the Meridian Repair Shop has closed entirely for all and everything?

If it were my pair (HP still uses Meridian M1 actives of probably a similar vintage to your M2 units) I would persevere. I put your question to him and he suggested you approach Colin Wonfor of EWA Ltd. You will find him in various parts of the AoS site.

HP told me that in 1979 he commissioned from Meridian a special pair of M1s with the electronics trays on long connecting chords rather than resting in a cavity within the cabinet. This was not due to microphony; it is doubtful if this aspect of performance had even been mooted back then.

The trays were done like this so that each of the six power amps had an external power supply rather than one shared between the three amps per channel. These were either the supplies from the 103 power amps or 105 power amps. He can't remember which.

The point being that on paper at least, your M2 electronics may have potential for multiple power supplies per channel. It's just a thought.

Customer service is very important - offer to go round and collect them :lol:

Hi Neil,
thanks for your feedback regarding the power supply.

Yes the Meridian Repair Shop is in the process of closing and is no longer accepting repairs, and will close in June this year. In some ways it saves me the stress of trying to package and send the amps to the other side of the world however it is sad to see them go as they have intermit knowledge of the workings of the 'legacy range' of the Meridians.

The local technicians here are a little in the dark re the Meridian workings so I was hoping to do my own research as what upgrades would be good.
Upgrading to separate power supply cables is relatively straightforward and something I intend to do however I would be interested in what upgrades / cap upgrades the other members have undertaken.

I will endeavour to be in touch with Colin Wonfor as you have suggested

Thanks again

Phil
