I am having to build a standalone PSU to remove the transformer hum that has plagued a recent phono build since the start (I tried to pack too much into a small enclosure).
The standalone PSU will house a transformer which is connected to a XLR jack which in turn will connect to the PSU input on my phono stage enclosure.
The question:
Should the XLR cable carry AC (12V-0V-12V) and have the rectifying done inside the phono stage?
or
Should the AC be rectified in the PSU standalone enclosure and then sent over the XLR in the form of DC (+12V/-12V) to be filtered and regulated in the phono enclosure?
or
Does it matter?
