I  know this thread has been dormant since 2013, but I thought I'd drop by and mention that Shiit Audio have just announced two remote controlled passive pre-amps, one single ended (Saga $350) and one balanced (Freya $700).
 
The announcement is here: http://schiit.com/news/news/schiit-previews-2-channel-line-at-rmaf
 
They should start shipping sometime in October 2016.
 
More Head-fi discussion starts here: post #12886
 
Cheers!
