I purchased an Oppo 105D today. I ran a coax cable to a digital input. I played the Emerson Lake and Palmer "Lucky Man" DVDA and was very disappointed. The resolution was lacking and poor 5.1 channel execution. I then played Roy Orbison's DVD and it sounded good. Why? I am not one to completely understand the technology and want to be sure I am not missing something.

My processor has 5.1 analog inputs and I am wondering if that would be a better connection for my Oppo.

I know the best solution is a HD621. If I were to buy the HD621, what would the connection be to the input of the HD621. I would like to understand why the HD621 is the solution for loosing MHR connection with my old G98? I want my DVD audio disks to sound as they did with my G98.

Thanks in advance for your help.
