Musical Fidelity M3 integrated


This amp is now a little long in the tooth I suppose. But I still love it. Mine is 100% original. I wonder how to change/upgrade the internal jumpers with something better and where do I buy new jumpers?

Other suggestions on how I can spueez better performance fron the unit?

Thanks.

Actually, he went whole hog and got some Lamm monos. He had a tube Lamm pre at first and then bought the kW line stage I had. His last purchase has been a AR Ref 5 line stage. Needless to say this is a very good sounding system. I hesitate to recommend any ICs as they are really a matter of personal taste. The best .5 meter ones I have tried are some solid silver Siltech with WBTs. I haven't used them for a while due to reorganizing my system. There is also an internal switch for selecting MM or MC that is not mentioned in the manual. Any good power cord will do; the problem is that they all sound different. Voodoo makes an adapter that allows you to use 15 amp cables; some of the 15 amp ones I have used are bigger and heavier than most 20 amp ones. My email is stanleywallen@yahoo.com if I can be any farther help.
I love my M3 and intend to keep it forever. I even have a spare set of nuvista tubes just in case. I have switched my phono to MC and run my Lyra Delos straight in. Excellent sound.
Good move, mr Manitunc. May I ask where to buy a spare set of nuvistas at a good price? I can see I'll keep my M3 for a long haul as well.

I must say it's tempting to send it to MuFi for an uppgrading, but it's quite exspensive...
I bought some also by searching the web by the part number; they were quite cheap for NOS parts. I would not have MF do the upgrade.
An update for those who are interested: As a precaution I've installed the new nuvistors (rca 6cw4) and replaced the ICs between pre-power as well (with 0.5m kimber pbj). It was a fairly easy job. No soldering at all. The amp is playing now. guess i'll have to wait for the tubes to "burn in" (for how long do you think?). As it's right now I can't tell any improvements.

Couldn't located the mm/mc but I'm in no hurry in this matter.

Thanks for your kind help :)
