George, to address your original question in the thread title: No, I don't think it is a valid test.

Why? It's the memory thing again that Bob Stuart demonstrated at the AES in December 2008 and at HH2. Your brain already "knows" all the detail that is obtainable from the hi-res recording. When you downsample it and introduce pre- (and post-) ringing, you brain has difficulty recognizing that anything is missing - it interpolates from memory.

Going the other way, upsampling and apodizing 44/16, your brain will detect new detail that it hasn't heard before, which is noticable.

For me, hearing things for the first time in my existing CD collection is the only way of knowing that my system is better.

Now that explaination is a great one. Same argument I used with Ron on being to familiar with a tune in the MP3 test. It all depends on which direction.

If you think listening to music is fun, try learning an instrument.
