A possibly relevant question is: "Is adding dither to this volume control something that will actually improve sound quality?" The answer may be: "No". The leading reason is: The volume control is somehow already dithered, you just can't see how. You can try to evaluate this by means of just listening, but doing so reliably takes a trained ear, and not that many people actually have them. The best way to train your ears to hear the bad effects of a volume control that is not properly dithered is with a known example of that failure. The worst way to train your ears is to read articles on the web by other audiophiles, which is very often a classic case of the blind leading the blind. Another way to detect an improperly dithered volume control is by means of technical tests. But doing them and properly interpreting the results is non trivial. The most common way that a volume control is dithered implicitly is by means of the low level noise that is present in just about all analog sources. Since any live recording starts out in the analog domain, this includes *everything* but carefully and purely digitally synthesized music. IOW not does all music that is recorded with microphones have enough low level noise to self-dither if played at regular volumes, so does even some synthesized music because most musicians are not all that careful about keeping their digitally synthesized music 100% in the digital domain. If a volume control is not properly dithered, it may actually fade the music into audible distortion on a slow manual fade out by means of that particular volume control. However, while that is an audible imperfection and would be nice to eliminate, it actually bears very little on normal listening. Note: other fade outs that are parts of recordings may still be clean. Hope this helps. ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=104629 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
