I own the Verite Closed headphones by ZMF. These have garnered high praise from the headphone audiophile community. I am personally astounded by their sonic excellence. I own the HiFiMAN HE1000 headphones, which I prefer to the SR 009 (which is sorely lacking in bass, to my ears; I haven’t heard the SR 009s headphones). I believe that my Verite Closed headphones may be even better than my HE1000 headphones.
I haven’t heard the Raal Sr1a or even the Abyss 1266 TC, but I will respectfully suggest that any discussion of the best headphone under $10,000 should include the Verite Closed by ZMF. An EPIC review by Josh Mound explains the stunning excellence of both the Verite Closed and Verite Open headphones.
