Ugly sounds when playing Sektor Radio

[amix]

All other radios I have in my library play fine, except these two stations:

http://89.223.45.5:8000/progressive-flac

http://89.223.45.5:8000/space-flac

I get very ugly distortion sounds, but not as part of the tune, instead they, somehow, come along with it, randomly.

More about the stations here (I only tested the two listed above).

Thank you very much!

P.S. Edited my initial post. What now is 'tune' was 'tube'. Autocorrect...
