hey jeff, i just got my v3 unit yesterday and i guess i should have asked earlier but are the only changes from v3 to a v4 the knobs and the upgraded software? I have the HK system so do I still need to purchase a line output converter. says on the unit itself it was made 05/2010 so i'm assuming it's a v3. Thanks for any help you can give me.
