WOW! I have to say something here. DPA has to be one of the finest microphone companies in the world. I am so impressed with everything I have from them. Their stuff is pricey but you know what, their workmanship shows why. I've always wanted a nice stereo bar so why not eh. Well hold me back... After a long wait from the time I ordered these to commercial production, I just received the SBS0400 Stereo Boom w. Shock Mounts and wow, this is designed like high end precession archery. The GM1500 piano goose necks are to die for. I'm looking at these and thinking, nice but how could they hold onto anything without falling over or off. Well did I say magnets! They have very strong magnet mounts coated in a smooth grip-like rubber that will attach to steel like I would never expect. The goose-necks and shock-mounts screw onto these magnets mounts so precisely, wow, so well made and clever. Not only are they great for sticking to the piano but I'm thinking much more. As an example. I have broadcast booms that I use for singing while tracking guitar. Stick-em on the boom at the right spot, no stand in the way. This could be perfect. I love this company, thank you DPA, this was worth the wait! thumb For those interested, here are some images: SBS0400 Stereo Boom GM1500 Piano Mounting Here's the technical info on the mounts: Cheers!
