On my system, it sounds like crap compared to my Santa Cruz card. I have these old (3 years) Harmon Kardon 2.1 simulated surround speakers that I plug into the Versa Jack on the Santa Cruz. From the Santa Cruz control panel I then select the output to be 4.1 Digital Out. I have no idea how/why it works given the speakers are not digital but it sounds awesome. If anyone knows what the heck I'm talking about please reply because I've been curious about this whole "Versa Jack" thing for a long time!
