Geoffkait ,I think you are right about the noise level...If someone dont care about the acoustical difference between headphones and speakers, this is the right track to travel...
But an old guy as I am like the acoustical freedom of his speakers also... The good news is I think it is possible, " in the grid", to reach relatively near, not too far behind, your quality "off the grid" system, with many precautions related to vibrations resonance, electrical embedding, and acoustical treatment and some other "tweaks"... I say "near" indeed because for the purity of the sound frequencies, the best speakers will always be most of the times only slightly behind the best headphones; but this acoustical, atmospheric freedom of the sound waves travelling to my body, out of the brain, we must recognize that this is indeed an another world... My best from my past to your future... :)
