I am also thinking about the construction of a  distribution amplifier with
15 or so outputs.  One thing that came to my mind, is that there may be
some point in  having one or two outputs where more money is spent. Then if
one thinks an item might be particularly sensitive to some aspect of the
reference,  one can use that.

One could for example have one or two outputs which have harmonics
suppressed 100 dB, without going to unnecessary expensive on all outputs.
