With the majority of the songs I listened to when I was listening to both the 009's and 007mk1's in the same day with my BHSE, most of the songs did sound better from the 009's, it's just the songs that sounded and sound uncomfortable with the 009's, didn't with the 007mk1's.
That's the only reason why I'd prefer the 007mk1 over the 009 when driven by the BHSE.
Hello David Maybe some songs sounded uncomfortable with the 009's because they were poorly recorded... Precision and acuity are mercyless. Conversely, with a fairly good sound system, everything sounds satisfactorly. Best regards
