Panel speakers is a good suggestion, and yes there are incredible headphones out there. I love my HiFiMan HE-5LEs (though they need some power-they actually sell an adaptor so you can hook them or the HE-6s up to your speaker amp).
I might also suggest going with a full range driver model, or something high efficiency. Their less complicated crossovers and lack of need for loads of power, translates into good detail at low volumes IME.
