I heard something recently that I had never heard before. On SWEET HOME ALABAMA at the 56 second mark. There is a background vocal saying SOUTHERN MAN. I like those little gems because it makes me feel like I am there with the performers when I hear those subtle sounds. I also think it adds to the musical experience.
The trick is for me to get this level of detail with no fatigue. I was listening to this above example on a tube headphone amp.
Just for curiosity’s sake, I just played the song on my KEF LS50 Meta and Benchmark preamp and amp with Lumin X1 DAC. You could hear it at the 56 mark too but if I did not know to listen for it, I would have missed it. Listening to the song on my headphones was a better experience because I was more immersed in the song. That is, I heard everything. My headphones are also known for extreme detail.
