Error in Upsampling Certain CDs?

Hello everyone, this thread is about upsampling CD players or D/A converter. I have noticed that on occassion my upsampling D/A does not work to upsample certain CDs, but will work just fine with others. For example, Pink Floyd, the Wall. The upsampling sounds absolutely horrible, the level is increased but there is all kinds of weird distortion and sound. Try disc 2 if you have it. When I swap with another CD there is no problem. Bought the Floyd cd in the '80's. So my question is whether you have found difficulties in upsampling certain music?

- anyone out there notice the same thing or close?

I recently ran across the following text at the Audio Research website (at http://www.audioresearch.com/CD3.htm) in a description of their new CD player-transport, the model CD3:

"While using the latest 24/192-capable Crystal DAC, the CD3 does not upsample, because our empirical research shows sonic compromise is unavoidable due to sample rate manipulation and approximating errors."

Is your CD clean and scratch free?? That may be the problem. I've also had friends tell me that some of their oldest CDs are deteriorating to some extent. THat could easily cause reading errors too.
