Smyth Realiser A16 sounds interesting. I want tp try that. Does it sound like a “room” ?What you experienced was air pressure waves (sound) produced by your ATC speakers, interacting with your room’s acoustics and then hitting your body. As DACs do not output air pressure waves (sound), only an analogue electrical signal, then obviously a DAC cannot provide “the magic lowends” you experienced.
Even HPs/IEMs can’t, although they obviously do produce sound pressure waves, because they only present sound to your head/ears. They do not present sound pressure waves that interact with your room acoustics and then hit your whole body. A potential solution, that’s good enough for some people, is simply to EQ more bass before the digital audio is converted and sent to your HPs. A better solution is to use something like a Symth Realiser, which processes the digital audio to emulate the effects of listening to speakers in a room by applying a personalised HRTF (head related transfer function) and convolution reverb. That obviously doesn’t solve the problem of the sound waves hitting your whole body but otherwise gets quite close to recreating the experience.
There are vests/straps available which produce haptic feedback that is supposed to emulate the sensation of low freqs hitting your body. I tried one once and personally didn’t like it much but some people feel they’re good. So potentially a Smyth Realiser A16, plus one of those vests/straps could recreate that “magic” you experienced with the ATCs but with HPs. The technology isn’t quite there yet to guarantee such a setup would work for you but it might get you close enough for you not to notice.

Thank you for the good explanation. It makes sense.
