Listening to Led Zeppelin III 24/94 Hi Res Remaster on Qobuz through headphones, the squeaking is obvious from the start until Jimmy ramps it at about the 45 second mark, especially if you are listening for it.
I'm Just Not Hearing It..., Do You???
I've been listening to Since I've Been Loving You but maybe it was lost in the transfer to CD because I remember hearing it in my youth (better ears?) on LP.
Do you hear it on your system and if so, does one media convey it better than another?
