I replaced my Project transport with the ET3 and could not be happier. The ET3 is built like a S__T brick house and is more detailed than the Project transport. It has a wide soundstage with instruments well placed within the soundstage. The only downside is difficult to read what track is playing because of the size of the display. Would i recommend the ET3 YES.
Have heard the regular centurion a while back, and after three month searching a cable that could give the Traillii more depth in soundstage and treble extension I decided that the Centurion is probably the best cable on the market for that purpose. Though I wouldn't say the Centurion is a perfect "upgrade" cable since it definitely affects the overall tuning of the IEM, the Centurion still has one of the best Soundstage performance out of all cables I tested and the most sophisticated mid-high to treble tuning which I found suitable for my current setup.
Also thanks Andrew for having it delivered flawlessly. The moment I saw the two gigantic boxes I realize how difficult this actually is.
its my best cd transport
Very nice sound with enhanced detail and note definition/timbre. Good solid bass which goes deep but very articulate as well. Mids given weight especially lower Mids . Very detailed and spacious . Treble nicely extended and detailed without getting sibilant or splashy . Very big stage as well stretching in all directions . And very good air
