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? 


I'm dealing with the same issue. No headphone jack on my Rega Elex-R. I'm planning to buy a budget headphone amp (and some Sennheisers too), feeding it with the "Record Out" jacks, which should not affect sound quality to speakers. 

You should at least look into a real headphone amp; what kind of budget would you be looking at? 

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!!!!
