Do you notice that ?
At about 9-10 seconds in, there is audible crackling in the left channel - confirmed this in the following issues :
- Polydor WG 800025-2 04 (10th anniversary box set)
- Polydor FR 800025-2 05
- Disques Dreyfus FR 824747-2 DCO 2000 MPO 01
- FDM 36141-2 DCO 824747-2 MPO 09 (1992)
Below Equinoxe III on CD between 1983-2011 : (6 Mastering)
Note: Since 1997, channels are reversed.
800 025 02 and 800 025 03 also have "peaks" on the left channel, but I do not hear the crackling noise (!).
The "first CD" (Polydor with red face - 800 025 01) has none of these peaks and therefore seems to me to be more faithful to the original recording.
The "MFSL" version (1995) is also excellent.
