How many systems do you have?

Three.  I am glad and fortunate to have three and those three perform different roles for me.  The first system is in the living room and is the grandest in scale.  The second is in the basement and  performs as kind of a rock n roll system while shooting pool and/or watching sports.  The last and my favorite is my nearfield system set up in a 9 x 11 room.  I get more satisfaction out of the smaller system sitting nearfield than the other two.  Being able to hear recordings on three different systems has allowed me to learn a lot about how rooms interact with the different systems, while also mixing and matching things like cables, cartridges and dacs.
