Musical Fidelity M3 integrated

If you are talking about the NuVista M3 any rca ic will do; of course length would be a problem. You could get custom lengths made. I suggest using a Bob's Devices SUT if you are using MC cartridges with the phono stage or a good external phono stage. It is still a very good unit; mine blew away a Mac 402 with matching pre a couple of years ago.

I came to the conclusion along with my friend who owned the Mac. On his Wilson Sasha the M3 was so much better he sold the Mac the next week. Yes, it has internal jumpers; they are short RCA ICs. I removed them when I wanted to try my kW line stage with the power section of the M3. The kW was better, after all it cost as much as the M3 just for the line stage, but not that much better. I have tried other power cords and there is an improvement. I also changed the umbilical cables for ones made by Sweetcome Audio in Hong Kong; they are not that expensive and a definite improvement. I also got a power cord from them. I have also used some PS Audio cords with a Voodoo adapter.

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 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.
