In Reply to: Dither does more than that, Page 426 of Robert Harley's "Complete Guide to High End Audio" posted by Teresa on September 14, 2006 at 01:26:34:
Like me, he takes a physical phenomena and tries to describe it in laymen audiophile terms.Dither is simply a superimposed noise floor--Nothing more nothing less. Noise does not shape or smooth a wave form it simply adds a background noise level from which low level detail can be more easily heard.
The low pass cap filter on an analog output section is chosen to provide the smoothest sound. It does not smooth the signal itself. By the way the caps on your solid state and tube preamps and amplifiers do the exact same thing. It would be fair to say that every electronic component in a high resolution circuit was selected and voiced to provide the smoothest frequency response, the best overall sound quality and generate the highest s/n possible. Harley was describing a components effect on the sound and oversimplifying even on this.
Please refer to AES papers on digital waveforms and playback. Not to Harley's guide as a professional reference. I bet Harley would tell you the same thing.
I believe the big difference in digital is when you buy the more expensive models and get a better analog output amp. Many skimp on this figuring the DA will be done at the receiver or HT control unit rather than at the device level.
I have no great love for digital, I am spending my budget on LP's. Not because they are better or even as good as a CD, simply because they are cheap and people are dropping off their collections to thrift stores in huge numbers. I get to reap the rewards of having a better than average playback system and lots of inexpensive software to select from.
Cheers!
