Opus 3 has some recordings on CD which originated on LP called "Depth of Image" and "Timbre" which are outstanding IMHO for your purposes. Opus 3 was selling a CD set over the internet. These recordings come with a description of what each track will reveal (or should if your system is set up right). The tracks are all simple mic recordings of vocal, instrumentals, small groups, choral etc, and use classical, jazz, and pop music, albeit with a Swedish accent. I personally prefer these by far over other available 'test' recordings. FWIW.
