I'm not sure how to interpret this.  I'm okay with the lack of battery due to being parked at my desktop, but it looks like I could be losing some potential headphone power output (at least from Normal/Turbo Mode).   Looks like it's 350mW vs 250mW in Eco Mode though.

  What would you recommend?  I saw you mention the iFi iDSD Micro in an earlier post but I think it's outside my budget.   Will the E10K that was mentioned still be viable?
