Seems like not. Here's one where I noticed a little tick from the CD rip. I decided to download the mp3 version from the site to verify (assuming they made the mp3 from their internal PCM file). Here's what I found:
And this exact track won a Grammy for best soloist performance with orchestra. And the sound is superb except for two blips like this about ¼s apart.
I don't know why but as of late these blips have become really noticeable whenever I am listening to music. There are a lot of these in weissenberg's recordings too, maybe left over from splicing!
