I am looking for general suggestions to reveal the great ideas that I usually miss.
I made converter tests many time, and it is not easy. First of all imo it is important that, if you compare two AD-converters, you feed both of them with the very exact same signal and calibrate them as good as you can with a test tone generator. Test like a singer sings one take in AD1, then one take in AD2 do not work at all, most likely one ends up to find the converter where she sung the better take better.
Alway test with stereo sources, as it is far more easy to hear the differences. A Guitar , A Grandpiano , and Cymbals are good things. Hear for the image and depth of field, and natural sound. Very cool fo check details is to record a bunch of keys.
I would splitt the ouptut of the micpreamplifier (on some a Y Cable is ok, some need impedancematched splitters) and then feed both converters.
Listening must be totally blind
