Happy Birthday!

If anyone from Sennheiser is reading this... I can't imagine there'd be any more deserving case for someone to receive a pair of HD800's - can you?

shame, but thanks for the quick reply.

I notice on the beezar website that only the black enclosure is listed Is this the end of the silver version or is there going to be another batch ordered?

I'm not entirely sure about buying Eagle, this is a bit like me buying my wife flowers... and a washing machine... As I understood it, the original intent was to show our gratitude and thank Alex for all his efforts but here we are discussing which headphone will allow him to design amps...

The headphone stand is a nice idea, perhaps a plaque could be added to commemorate the whole thing, not names per se but the community

Sorry, it's taken me while to get round to this. Have now sent a small contribution to the fund. Very happy to see Alex rewarded for his generosity and infinite patience UB

Ferrari Thank you for your very kind offer. I do like the amp very much and a building a new one is a definite possibility. But I'm not going to give up on this one just yet. Besides if I do find the fault and fix it, it may give some clues as to the hiss problems reported by some IEM users.

thanks for the suggestions, I'll keep you posted.
