Just a thought, not sure where you're located but ebay UK frequently offers up old full width/half height Naim NAP90/2 or 3 amps pretty cheap, in the end same cost as what it would cost you to clone a Headline. I think a 90/2 could be easily converted to a headphone amp and look pretty cool too, if you can source a proper Naim knob for the volume or! use a remote only with the motorized pot internal and then you just need a tiny IR window cut into the front.
I'm usually against butchery of old equipment but hacking those half height 90 series wouldn't upset me much. The NAP90/2 would really be a traditional Naim output stage headphone amp exactly the same as the NAITs 1/2/3 as it's a differential amp unlike the single rail cap coupled Headline.
Anyway, it would be an interesting experiment.
Correct I trying this I connect headphones in to NAP140 boards but sound is different.But you mentioned somewhere else the use of NAP circuit minus output devices as a headphone amp...?
