"Side by side" could itself cause a subtle difference.
Better option would have been to use one mic and a mic-splitter. But
that would defeat the point of a mic preamp test ;-/
** A Rode NT-1A ( source Z = 100ohms) could easily drive several pre-amps at once.
The output level is very high ( 35mV at 94dB SPL) so pre-amp self noise is a non issue.
The dopey OP needed to make a Y lead and match gains to a fraction a dB - a basic DMM could do this with a steady sound source.
