I own BHSE #233, which was shipped to me by Justin mid October. You definitely have a very recent one from the latest batch.
The power supply of the BHSE is typically configured by Justin for the country it ships to (unless explicitly requested otherwise). If it was originally shipped by HeadAmp to Australia, it would be configured for the voltage used in Australia. So yes, there are multiple configurations out there, ranging from 100V up till 240V.
My BHSE is serial #246 and is from batch #4 which is the last batch and I received mine early November.
Justin burns them in before shipping, so just use it and enjoy! It is the best sounding amp out of the 3 I've heard with the 009…no complaints at all!
Many Thanks to both of you.
For some time now I have had the Stax SR 009 with the Stax SRM 007t11 amp and whilst the sound was great I thought it could be a lot better and so my quest to find the best amp finally started about a month ago.
During that time I went though a situation as to maybe change the earphone to the highly recommended Abyss AB-1266 planer earphones, but again where I live the nearest dealer is over 4000 kms by car or plane. I even contacted the manufacture to see if they could help, There response was "No they could not help and just buy a pair, sell them if you dont like them" so that response immediately put a big NO in my decision making.
I cant wait for my BHSE to arrive and finally hear what the 009 is truly capable off.
