I had a 3A and now have the 3B. It is night and day difference. The switching is now done by relays and the noise floor is much lower which makes for a much quieter preamp.

Question for any and all M3a owners??? Anyone know the year the last factory "mod/update/upgrade" was done to this unit, so one knows if he has the latest greatest M3a??? Also, mine was purchased as a "factory refurbished unit" & came with the Russian 6H23nEB tubes in 2014, system includes new Aragon 8008( Indy Labs), Linn LP-12, Ittok LVII, Van Den Hul MM-1, Marantz UD8004 Blue ray, & Maggie 1.6's. Question/opinion even if my M3a is the "latest greatest", would the cost of moving to a M3b make my system that much better??? Thank You Kindly
