I have a Yamaha DSPa-595a and a Pioneer 626D DVD Player. I use an IXOS Coaxial Cable to connect it to my DVD Player. The sound is fantasic, however I am trying to think of ways of improving it furthur. I was reading the Review of the Pioneer on this site and HC said that they could not tell the difference between the Onboard decoder on the Pioneer and a Yamaha DSP-A1. This got me thinking. If I used my Pioneer to decode the signal instead of the Amplifer then would i get any improvment in performance? (this would be done using the 6 channel inputs). Well? Any help would be grateful!
