That said, there are many examples of recordings original made for mono reproduction (which includes just about every "popular" recording from the invention of the gramophone to the mid 1060s) that are now available on CD. The info you've been given is correct in that all commercial CDs confirming to the "red book" standard have two audio streams, intended to be used as the left and right channels of stereo recordings. However, when a 30th anniversary edition was being prepared for CD release it was discovered that the so-called "mono" recording was actually "slightly stereo" - not enough to be able to be able to place different instruments across the soundfield but just enough to give a better perception of separation. Feelgood released their debut album in the mid-70s it was marketing as being mono, part of their retro back-to-basics sound and image. Most people can't distinguish a genuine mono source to a stereo recording with very limited spatial information. and even the most extensive, esoteric equipment will not produce identical audio output even if the data on the CD is genuinely a doubled mono track. Lastly, as soon as you play a CD the data streams are going through D>A processing and then through a pre-amp, amplifier and speakers/headphones. Also, given recent trends in CD mastering techniques engineers may tweak the original source to make it sound "better" (usually just louder). Don't forget that audio CDs are designed to apply a form error correction (more correctly, interpolation) when samples are not read correctly due to manufacturing flaws, damage, dirt, misaligned lasers, etc. There are many reasons why two identical (mono) tracks may sound slightly different, or produce slightly different results on metering equipment.
