Hard to tell if this could be a successful product but it’s certainly appealing to the people who love to A/B test everything. The main reason I purchased an Ifi zen one signature was for the dual output plus the coax spdif out all working at the same time. That way I could have two DACs each going to two separate amplifiers (using the X8 dac). Unfortunately I didn’t really like the zen one dac with the zen can so I always ended up just using the x8 and the zen one was just a DDC so what was really the point in that case.
