Thank you all for your suggestions.
BUT:
I really need to hear from people who have actually heard this cd (Telarc 2CD-80506-- Dvorak: Stabat Mater). I do not have this problem with other Telarcs of equal quality and dynamics. It is the fact that I acquired a second copy and found that it, too, displays the same flaws at the same places that made me think of a defective cd in the first place.
I have listened at low levels and the distortion is still present.
I am using an Audible Illusions Modulus 3a. I am feeding it with a Jolida 1000a player which has a low-normal output and is extremely unlikely to be overloading that preamp. I am driving Shahinian Hawks with a Plinius SA100III.
It is THIS cd, in two different pressings, about which I am curious.
I appreciate all comments, nevertheless.
