Just ordered the HagUSB. He does live in Hawaii and shipping should be only one day. He said it will ship out tomorrow so I should have it by Friday. Can't wait to try it out with the 840C. I noticed there is a sticker on the 840C that says, "Ipod Command, this remotes product will control your Ipod via a compatible docking station". I didn't see anything in the manual yet, but I've been too busy listening to my music though. I'll post some impressions of the 840c later. Also, I'll post up some impressions of the HagUSB once I get it in. I have a DAC1 and a DA100 to compare it to
