Offered for sale is a like-new condition McIntosh MHA150 Headphone Amplifier. I am the original owner and it was purchased as a new-in-the-box unit from an USA Authorized McIntosh dealer. Great sounding and very versatile piece as it also includes a built-in DSD DAC as well as a 50 watt per...

Power supply directly below, to the right 009's reside in their wooden box between listening sessions.

Back on track...

Peter Walker, the founder of Quad, used to say that the volume control should be used almost like a focus control (much like that of a camera lens) to 'place' the sound stage correctly relative to the listener; in other words, there is a 'right' volume for each recording.

So I take it no Peter Belt foil squares or his "electret cream" residing in your system?

Oh what fun awaits you! I assume that those are Gamma Pro's and Sigma Pro or Sigma/404? BHSE will bring them to their full (and most likely ultimate) potential. Awesome collection!!

Agreed if one is speaking of true balanced (differential) circuit topology versus "faux-balanced" which, unfortunately, is all too common in many of the components that feature XLR inputs and/or outputs.

Brian Eno on the BHSE/009 = Crazy Good!!

All this new BHSE goodness is so exciting to hear; knowing the sense of joy and wonderment that awaits the recipients of this batch warms my heart. Trust me, the mundane aspects of having to utilize longer cables, etc. will become meaningless once you get lost in the sheer majesty of the sound...

I am still wondering about the reliability and longevity of the PV tubes; sound notwithstanding...I know from experience that NOS (UK) Mullards were built for the long-haul.    With that being said I do not have any to use in the BHSE at the moment but from what I gather in that circuit they...

I recall a while back that Justin indicated that the next batch of BHSE would most likely be the last. Insofar that from the beginning it was a "Special Edition" and thus would be a limited production item. And also due to the fact that many of the high-voltage parts are becoming quite scarce...

"It's like, how much more black could this be? and the answer is none. None more black."

Yes, the sad reality is that with the demise of CRT televisions and monitors there is really no mass-market applications left for the particular high voltage parts that are used in the BHSE so they are becoming extinct.   The BHSE while using tubes is essentially a solid state amp at its core...

Not to mention if the BHSE was sold via normal retail channels it would cost at least $10,000-$12,000, possibly even more.

How many BHSE is Justin making in this batch?
