ASTELL&KERN A&ULTIMA SP2000T PORTABLE DIGITAL MUSIC PLAYER $2499 REVIEW

One issue the SP2000T seemed to solve, which was a worry, is microphonic distortion. I mentioned this earlier in my review. If you are familiar with tube gear, just touching a tube will generate a vibration that you will hear as an unpleasant audio signal. I wondered if that would be a problem in a tightly packed device. Turns out, it isn’t. Astell&Kern have come up with a floating magnetic structure for the tube mount, and in my tests, sound emerges from a silent background, even when I tap the case.
Listening in a pure solid-state mode, I found the results hyper-realistic. Again, with rock or some new age, this was not a disadvantage. For example, in the track ‘Disc Wars’ from the Tron: Legacy album, I preferred the solid-state amp sound.
