So... it outperformed the X1??
To be direct, yes. The N-01XD sounds more refined, bigger stage, quieter. And, it has more flexibility as it has digital inputs which the X1 lacks.
Now, the N-01XD costs 40% more than the Lumin X1. Therefore, it should be more flexible and sound better. However, in high end audio, higher price is not always a guarantee of better performance but, in this case, it is.
Lastly, the Lumin X1 is an excellent product. I’m not dissatisfied or disappointed at all.
