I concur with everybody on this thread. If you like a warm sound and the money is tight, B&K is wonderful for the money. I have a ST140 (precursor of the 2140) and have used it in my system for 9 years. I just replaced it this spring with a used B&K, EX4420 (225/channel) for $600 used (money is tight for me). The sound is a little less warm but is still sweet and certainly slightly more transparent. I am happy with my choice.
You might want to give Klaus a call, from what I've heard and read, if he does not think the rest of your system, he actually may recommend another product. It should be noted that the Stratos is supposed to have an entirely different sound, being very transparent and quick. It really is about what you might prefer. The Stratos is also supposed to have a very long burn in period. YMMV. I have never heard the Stratos, so I cannot speak from personal experience.
Good luck.
