It is still a nice powercable, but in technique it is not the best anymore. Quality is Always based on the moment. After time it changes.
Newer powercables like the Purist Audio go further in parts as black level, articulation of voices, intimate stage and even drive, control and dynamics.
MIT needs to do more research in technique to catch up. In all the comparisons with MIT cables I can make the conclussion that they are behind some other brands. It has become quite easy to create a higher level with cables like Audioquest and Purist Audio.
