@brianlucey That's exactly what I did Naim was supposed to be good and class A but I compare my headphone setup with my personal system and it sounds more like my Genelec system. I think the headphones are good what would be a suggestion for the amp/dac? I definitely think headphones need tube amps just on a guess, tubes sound much better to me and if I need to monitor for accuracy the ss system, but for fun the tube system.
Also I understand your philosophy of sound but it is self refuting if you think about it, ultimately sound being recorded as accurately as possible rather than sounding better subjectively is best practice. Our brains just like sex are the most important organ in hearing and interpreting music but the standard is nature and real acoustic instruments along with natural sounds we hear everyday. Our brains will always hold real sounds as a base line. I remember the B&K omni measurement mic was considered the only accurate reference mic for many years by a government measurement group.
