Of course. This is why I listen a lot at 176.4 k upwards (upsample or native); to push the effect of the brickwall filter up the f scale. dCS and others have variable filter settings but one is forever fiddling with it and I tend to settle on one of them. A lot of Cds and DVDs are not mastered well either. Often there is a peak of 10-20dB at hf and filtering this out with a FFT filter in Audition can work wonders. Some attribute this to TV monitor breakthrough at 15.7 kHz but can occur up to 21kHz for CDs. Resampling artefacts is only one of the issues. With Audition, I always do pre-post filtering although I don't know excatly what this does. The 400 page Cool Edit Manual and posts on the web just serves to muddle waters.

A CD system is much more difficult to set up well than an analog system.
A PC audio system is even more difficult because of software, hardware and power supply and clock issues - much of it being junk in audio terms.

I have been pointing out these issues in response to those who promote PC audio as superior to high end boxes and some are now at least admitting that there are problems. Sad thing is, we are no where near solving them in every day use.
