I have a Rode NT1 (not the newer NT1A) and am pretty happy with it. I have a ART Pro MPA and ART Pro VLA and am interested in doing a little stereo tracking (upright piano, acoustic guitar) I have thought about getting a pair of the Kel HM1's but was thinking that maybe I should should just ante up for another NT1 and then go for a more expensive mic for other applications lateron like a AT4050 or Rode K2. I can pick up a brand new NT1 at a local shop for $200 Cdn plus tax with shockmount. My question is, if I buy another NT1, they will not be a matched pair. How important is this for a home studio?
