Yes--been waiting for these. FYI-- I've ordered a green 3x 22.5mm vial from mixglo.com. It's legal to buy tritium vials, just illegal for US companies to sell them.
andyThanks Andy! I was looking forward to building the BH Crack, but in a moment of weakness, I bought an Audeze LCD-X and had to sell a bunch of other stuff, including the Crack. Amazing headphones--no regrets, but will have to put off the Crack for a bit. You guys have been doing a lot of nice head-fi stuff lately.
