Yeah it would be fantastic if there more impressions regarding the Black Diamond in general. I've done quite a bit of research and can only find a handful of posts that could be considered as such. Even the ECP thread over yonder is devoid of any real solid impressions on the BD, let alone ones comparing it with the DSHA-1 and L-2.
At this point I'm definitely open to the BD. I've had one gentleman contact me considering selling his L-2 but nothing has been finalized yet. I'm also eyeballing the Ragnarok assuming it actually gets released for sale to the public anytime soon. I thought I had read somewhere that Doug was down to his last BD unit for sale, however I read that almost a month ago and his ordering page is still up and the BD can be added to the shopping cart.
Just FYI whatever I buy I'll be pairing with the HD800, hence why I've been so interested in the L-2 as of late.
