I am excited to hear about the coming Bryston headphone amps. I have been a headphone enthusiast for a few years now.
In the last few years, a company by the name of “Head-direct/Hifiman” (http://www.head-direct.com/
) has emerged from seemingly nowhere to garner quite a following for its highly acclaimed products catering to the portable audio crowd as well as serious headphone users. In particular, their “HE-6” Orthodynamic headphones have been making waves on www.head-fi.org
with some users preferring them to flagship models from established headphone makers such as Stax (SR-007 Omega 2), Sennheiser (HD800), Beyerdynamics (T1), AKG (701/702) & Grados (PS-1000) & Ultrasone. However, these "HE-6" headphones are notoriously difficult to drive. Some experienced and serious headphone users are (subjectively) of the opinion that even some very notable high-end headphone amplifiers do not have enough power to drive them optimally. These users are resorting to driving them out of the speaker terminals of amplifiers (of course we are not talking about 28B’s!). I do not know how true the comments are as I have not heard the "HE-6" myself (but am considering a pair sometime). This search will yield many references to it: http://www.head-fi.org/search.php?search=HE6
I know that you are testing several high-end headphones with the prototype Bryston headphone amp. If it’s not too late and if you think it’s worth the effort, could you lay your hands on a pair of “HE-6” and run some tests? Thank you
