Gramophone Dreams #35: ZMF & Hagerman headphones & headphone amplifiers

Almost a year ago, a headphone pal loaned me the Zach Mehrbach–designed ZMF Auteur LTD headphones. He said, “Herb, see if you like these.” I took them home and right away thought, Wow, these headphones really disappear!

Nothing about their sound attracted my attention. The only thing I noticed, casually, was how relaxed and unbelievably transparent they were.
