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.
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?
