Musical Fidelity M3 integrated

Thank you for your reply. I thought there are internal jumpers between the pre- and the power section. Maybe I've mistaken?

What a surprise that the M3 blew the Mac 402 with matching pre. How do you come to this conclusion? Have you change the main power cord to the power suply?

Looks like I'm stuck with the M3 for a while, but I can live with that :)

Wow, so he sold the exspensive Mac?! What a change of fortune! I guess he got himself his own M3 then. I'll try to open the M3 soon to get a clearer picture of what to do. I have a spare 0.5 meter of Kimber Kable PBJ. Do you think they'll do the trick or should I get something else? Mine umbilical cables are from Kimber Kable as well, and I'll get in touch with Sweetcome Audio to see if they still sell a suitable power cord for the M3.

You've been very helpfull, sir! :)

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...

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 :)
