I have a Steinway B, and I have a few favorite set-ups.
For a close sound, I like to use a pair of Oktava Mk012 (cardioid capsule), one on the upper register near the hammers, the other over the bass strings near the string crossover point, and then a third mic (usually something like an RE20 or a Shure Beta 52) under the piano pointing up at the soundboard.
For a more "natural" sound, I'll often use a M/S setup with an AKG414 for the sides, and a Neumann TLM 103 or a mono ribbon mic for the mid. I have a pair of Cascade Fathead ribbons that I sometimes use as a spaced pair, as well, for a more "vintage-y" sound. That M/S or stereo setup goes about 3-4' from the full-stick open lid, about 5' off the ground, and aimed very slightly down. That's specific to my room which has lots of acoustic treatment but relatively low ceilings - that position gives me the best balance between piano and room sound.
The discussion about AEA mics got my gear lust all fired up, too. I have been a fan of the AEA R84 and R88 for years, but I hadn't even heard of the N8 - now I really want one (or a pair!)
