"Second, many of the reference recordings used to judge the improvement in equipment are 50 years old. I find that ironic. Finally, the recording equipment used to make the reference recordings was retired as obsolete by 1970. Commercial considerations forced this change. The newer equipment was better suited for multitrack/overdub recordings. That's not ironic, but sad. Although it's interesting to note that some vintage recording equipment (50 year old stuff) is highly prized by recording engineers."
Going back to what I said in my first post, I really don't see why the age of a recording matters all that much when used it to evaluate new equipment. You still want to get the most out of the music and the equipment. Let me give a different example. Going back 50 years or so, the technology used in the studio, and that used in playback systems were not equal. I think recording equipment was far more advanced in SQ than playback gear. So, as home stereo evolved and got better in just about every way possible, newer equipment is now able to get a lot more out of an old recording.
Look at it from another angle. If you took a well produced 50 year old record and played it on high quality equipment from that period, and then put the same record on modern equipment of the same quality, chances are you'll hear a lot more of what's on the record. If modern equipment wasn't able to get any more out of a recording than vintage gear, then SQ should be about the same playing the record on either system.
