Highend tube preamp w/no headphone jack - help I wanna get a pair of phones

I have a deHavilland UltaVerve tube preamp. Sounds amazing but thinking about getting a pair of Sennheiser HD 560S phones. The preamp has no phone jack. But does have two sets of RCA outputs. One goes to my amp - the other is unused. 

Can I use these somehow to drive the headphones? Would I need some sort of headphone amp to go between? Figure anything I add can potentially mess up the sound (this preamp is incredibly holographic, with a wide and focus sound stage - besides the warm musicality that tubes usually have.

Any suggestions? 


Nice preamp!  I’d suggest a good tube headphone amp you can hook up to your spare output.  Quicksilver makes a highly regarded amp that’s not insanely priced.  Just one option.  Also, do some research on headphones as you would with speakers as that choice will be critical to your ultimate enjoyment.  Best of luck. 

@soix - Totally agree - I used a Quicksilver Headphone amp for about 6 months before I replaced it with an Eddie Current Studio B; that Quicksilver, for under $1000, is a GREAT DEAL!!!! 

@slaw I’d be VERY interested in your thoughts on the LSA as you and I have similar ears as to how we hear the LavriCables.  I know you have Sundaras and I’ve got both HE400S and Arya Stealths so pretty sure your experience will translate well to my sitch.  Please follow up with your thoughts — after burn-in of course — as I think I want to write a formal review of this unit on my site at some point.
