Re hum. Yes the Miyajimas can cause hum issues. I have a Zero and while I love it you will need to solve hum problems
The best solution is to use a phono stage or step up with a ground that can be lifted. Either that or having a mono switch on your amp. The latter causes (in my experience using an ARC Ref40) a slight drop in dynamics. My Music First step up has a three way ground switch and this clears all hum issues. The other suggested solution of using only one channel still left me with hum (which is clearly out of phase in each channel as the mono switch cancels it)
anyway expect hum and expect to need to work on dealing with it
