Is That A Violin I'm Hearing?

Know exactly what you're referring to. That's not it. That pitch change is audible without adjusting the volume. The violin part is VERY low level, I'm guessing down 60 dB or so. It happens after the heartbeat fades out. There is so much time (maybe 20-30 secs or more) between  the heartbeat stopping and finally  the disc stopping that I got curious if anything was still recorded...

To put it in context, my volume control reads from "0" to "150". I was playing the album with the control set to read "42". That corresponded to an SPL peak level of about 75 dB (didn't use my RS SPL meter, but I've gotten pretty good at guessing from using it so much)!!! 
As the heartbeat faded I turned the volume up to read "110" in order to be able to hear the violin. It only played for 10 seconds or so, and was barely audible above the room noise of around 40 dB.
FWIW, this is an SACD remaster from 2003.

And lest anyone think I'm "hearing voices", I had a buddy over at the time and he heard it too.

I found my case, but I'm missing the SACD surround copy. Bummer. apparently it's worth about $100.

No problem, teo, come listen to my system.
