Keep in mind that i'm only testing the conversion and not the preamps. The preamps on the traveler to my ears are not professional quality. I knew that going in because the difference is night and day. It's more difficult for me to hear the differences in AD conversion quality between the metric halo and traveler. Therefore, this test isolated the only variable to be the converters. In fact, it seems as though most people prefer the sound of the traveler. It would be nice if we had some professional engineers chime in here with solution and/or opinions! i'm just a lowly musician myself!
