Mic Splitter box, any recommendations? I want it for comparing various preamps . Would this work: pro/ cons?

The Pro Co Sound MS3 3-Way Microphone Splitter Box is a portable utility used to split the low impedance signal of a microphone into 3 outputs. The result allows 3 microphone preamplifiers or mixer channels to be fed from one source. The MS3 features a single XLR female input, a single XLR male direct output, and 2 XLR male isolated outputs. The isolated outputs feature a ground lift switch which eliminates hum and electrostatic noise. Transformerless components feature additional electrostatic shielding for even further protection against noise.

Ground Lift Switch
The MS-3 features 2 isolated outputs with a ground lift switch that eliminate noise, plus a single direct output
Transformer Isolation
Transformer isolated circuitry eliminates hum and noise due to ground and radio frequency interference

Splitters do also introduce other problems like what happens when there's a cable fault - in particular a short. In transformer coupled designs, you might lose a couple of dB if one of the outputs is shorted, but with with a simple parallel split, a short anywhere is 100% destructive. Unplugging a parallel split is also quite noisy - with loud pops and bangs, while the transformer version copes better.

This has the useful diagram showing how phantom is fed through - Sowters feature in lots of UK designed products - the UK equivalent of Jensen.
