I am really on the fence on this one.
Knowing what I've experienced with my Sunfire TGIV, I switched it out for something more modern but still capable of using all five of my Carver amps. It has optical, digital, pre outs along with HDMI. Will I use them all, probably not but I have them if required, plus a 5 year warranty.
For the Sunfire, when the processor craps out its a big paperweight as it can't be fixed from what I was told.
