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.
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)?
