HeadAmp Blue Hawaii HP amp


I know this Amp is excellent for powering the Stax headphones. Can the Blue Hawaii also power other headphones that have XLR connectors? I am thinking of purchasing the Stax SR-007 or 009 in the future but in the meantime would the Blue Hawaii power my Hifiman HE-6 and Sennheiser HD-650? And if yes would it power them well or poorly (too powerful of an amp for the headphones)?

I know it's been a long time since any responses to this thread but can anyone give me a clue?  How happy would I be with the bass from Johnny "Guitar" Watson's, "A Real Mother For Ya?" or "One Sweet Day" by Mariah Carey and Boyz 2 Men? or Michael Jackson's "Bad?" or some extremely heavy bass like in "Angel" by Massive Attack? If I'm going to pay nearly $10K for a headphone setup, it will have to be able to bring me utter delight from every high quality file I send its way. So please tell me "exactly" what kind of bass can I expect.
A BHSE with 007 or 009 will give you much more satisfying bass than the HD800 for sure. I never liked the Sennheisers, and lack of bass was one of the big reasons why. I’m still scratching my head as to why the HD800 has had such a stellar reputation all these years. Again Stax isn’t for bass heads, but they can deliver enough bass impact for many audiophiles, including myself. The balance of the 009/BHSE is sort of roughly comparable to the Focal Utopia.

If you’re still worried about bass, the 007 can give a more overall energy down low than the 009. Though the 009 is more fast and precise and can still slam - I prefer them. The KGSShv Carbon will also give a bit more bass impact and extension than the BHSE, but I prefer the sweeter midrange and overall sound of the BHSE. A Carbon paired with 007 will give you the most bass this side of a DIY T2 (which is an absurdly wonderful amp).
I have heard the Blue Hawaii amps at stereo shows and they are impressive. I have been watching Audiogon and ebay for years and almost NEVER see them for sale. They are expensive and the wait for them to be built can be several months. 
the place to look is US Audio Mart. lots of headphone’s and headphone amps there. many more listings and easier to navigate. and free to post and purchase too.

you can read my 2017 post above in this thread. the BHSE headphone amp is the real deal.
And let me add that a buying brand new BHSE is a stellar deal (especially in the context of high-end audio), and you’d also be supporting a great American small business in these trying times. The used prices aren’t discounted very much anyways.
