One of the main pleasures in this obscure hobby of ours is coming across something that no-one else seems to know about, but absolutely blows you away with something you've never heard or seen before (music/gear/apps/whatever). As this site is based around the concept of people suggesting gear that others might like and then helping them get hold of it as cheaply as possible, I figured this would be a good place to start!
List your "Undiscovered gems" here - it can be a firm, a specific IEM/headphone/piece of gear you can't live without - anything you think people may not have come across in their audio travels. Who knows, if enough people like it, we might even see the MD guys run a drop for it! ;)
