If you are interested, here’s how this topic started. http://www.hometheaterforum.com/htfo...hreadid=202548 Update……..this past weekend I did some informal testing with the following formats for playback quality through my Toslink and Hi-Res analog connections; DTS, DD and redbook. First, before anyone asks me, let me state that I’m using Better Cables Silver Serpent toslink and analog cables. I tried to adjust the b/m and sub settings so both connections would be equal. I used my analog R.S. meter and listened at approximately 85db to all formats. The results were somewhat surprising. In every format the toslink connection easily had more clarity and depth. For example, I listened to the Eric Clapton’s: Live at Hyde Park DVD in DTS mode. The depth of field had a “3D” sound stage effect in toslink playback. The vocals were more distinct and pronounced. Clapton’s guitar had a more “intense” or “raw” sound that wasn’t there on the analog playback. I also listened to John Fogerty’s Premonition (DD) and Sarah Brightman’s LaLuna (DTS) concert DVD’s. The Brightman DVD in analog playback almost sounded “veiled”. As if I was listening behind a curtain. Overall, when playing the DTS and DD formats the difference between optic and analog was not “Night & Day”, but it was very noticeable. When playing redbook media the difference was not as dramatic, but it was still noticeable. Considering the cost of the player, I had thought that my 2900 DAC’s would have faired better against my h/k AVR-525. Has anyone else had similar or different results? I'd like to hear your feedback.
