How to get more volume from my HI FIman 400se phones


I purchased a pair of HIFIMAN 400SE Phones im using with a 38w Yaquin tube amp with no headphone input..im using an IZEN dac/headphone jack...The phones are 25 ohm...I get very low volume at full gain...Anything i can do short of replacing the headphones?

Thank you friends!..I had an idea of exactly what you both advised but wanted to make sure...Im grateful!.....I used to own Grados and Sennheiser 414 which i loved..( i wanted to maybe stay with a closed ear system....Both of these were very efficient without a headphone amp AND sounded great per my system investment ,which is on the lower end.....i also  have a cheap pair of audio technica phones that play loud  but leave me with massive earaches....Again,thanks for advice!
