From the Stereophile review, a rebuttal from the first reviewer:
In order to answer that question, I have purchased and studied at least 80 genuine (analogue) “master tapes” taken directly from the archives of RCA. Many of them I played back on the exact Ampex machines they were recorded on (which I also purchased). Virtually all of them sounded VERY “pleasing good” and therefore, by your definition, must ALSO have sounded accurate good. In truth, I can’t remember hearing too many bad sounding master tapes.
For my reviews I always use high-res “master” files supplied to me by the recordist for that purpose. When I finished my BP/BM comparison, I told JA about my own “alarming audiophile episode” with Macy Gray’s HDTracks album “Stripped,” wherein the BP DAC reproduced pretty much exactly what I heard sitting behind the binaural head at the former church in Greenpoint and the Benchmark DAC3 which did not even get close. It conspicuously stripped away a huge amounts of what I and David Chesky know is on the recording.
I use Chesky recording sessions to review headphones because I can compare what I hear live to the sound coming off the so-called “mike feed.” The Border Patrol DAC reproduced the church walls, the reverb, the positions on the floor where the musicians were standing, and all the subtle breathiness of Macy Gray’s voice. With the Benchmark, the majority of that information (which is definitely on the master file and appears via David’s $100K MSB DAC and via my Holo Spring DAC) disappeared !!! Your neutral DAC “stripped” away information that is unquestionably on the master file. Not to mention the BM DAC made it sound hard cold and harmonically threadbare. I call this subtractive distortion. Did you measure any of that?
It’s all in the ear of the beholder.
All the best,
