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've never had any problems with upsampling. Can't recall if have "The Wall" on disc, but if i do, i'll try giving it a spin tonight and see what happens. Sean

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.

Phild, that's a great diagnosis, are you a doctor? In 1988 at a frat party my date spilled a beer on a rack of my cd's including this one, the paper inserts to this day are moldy its not that gross). Of course a cd this old is gonna have some scratches, so I cleaned the CD and now it skips on track 1. However, it still has the problems with upsampling, and this is on every track, across the whole disk, on both disks. So either the CD is going bad or there is something else. I have older CD's that were also slimed but which are unaffected. Anyone else?
