Classical Music Listening is number one for me in this time of my musical evolution. @ one point it was Blues, then Jazz, New Age, World, ...
Now it is Classical, and it has been for several years; I love all, from solo piano, to chamber classical music, to full orchestral works, between chorals, operas, and the full classical gamut...be it two-channel stereo or multichannel (3.1, 4.1, 5.1, 6.1, 7.1 and all those numbers of channels sans the sub, .0).
And it can be from many sources as well; digital and analog. ...CDs, SACDs, LPs, DVD Audios, Blu-ray Audios, DVD Video classical music concerts, Blu-ray Video classical music concerts, Hi-res audio streaming and downloads, R-2-R tapes, cassette tapes, 8-track tapes, ...everything Classical Music.
...Even youtube classical music video tunes, and iTunes, and the full palette of classical radio stations; HD Radio, Pandora, Sirius, FM analog stereo, ALL Classical Music. ...And strictly Classical Music.
Right now I am listening to this:
...In Stereo (SACD).
