I expect this question been asked many times before but could you use a SPDIF to HDMI convertor to send only the audio portion ofthe 598 to the HD621 using something like this

Or would be better of retiring the 598 for a Bluray player to handle my audio/DVD needs .The Bluray player will be next on the list after buying a HD621 .How would the 598 compare against an Oppo or a zune through a HD621 and would these players be my best choice around the 600 pound mark ? Any suggestions or experience in this matter would be greatly appreciated .
