Old typeface? They haven't changed it. They just extended the T to line up with the A and changed the main station's holding shape to match Xtra's because they removed the frequency from the logo.

The typeface has changed, actually, swapping out ITC Avant Garde Gothic (as in the previous logo and "Dance" type) for Campton (compare the "C" letterforms between the first post and the old logo in the SoundCloud link). The change does appear quite slight at first, but having already seen the font in action in the current look of Germany's ProSieben, I noticed it right away.
