I have a Blackbird (with MMF-7 TT and PH-3 phonostage) and it took a really long time to break in. Also the Blackbird will reveal any problems you have with other components.
The Blackbird comes with a really good booklet that you should follow. It recommends about 1 degree negative VTA (front of arm higher than back). Of course your experience may vary.
It also recommends readjusting after at least 50 hours becuase the "suspension" of the cartridge will soften up as it is broken in. So really there are two break-ins going on, electronically and mechanically. Of course if your phono stage is being used for the first time you have three breakin periods. Even more if your cables are new too.
BTW, if you are using the cables that came with the TT I am assuming it is the same stuff that is used with the Music Hall TT and that cable is cr-p so you may want to try a new one. Hang in there and readjust VTA and VTF after about 50-60 full LPs. Reassess your options after that.
