Hi, 
I am fairly new to Audio Circle, this is my first post in the ACI category.  
I bought a Titan XL last summer off Audiogon, and I love it.  It is a wonderful compliment to Magnepan 3.6's.  Smooth, powerfull, coherent, and it goes real deep too!,  But most of you already know that.  I was going to get a REL B2 or 3, I am very happy, maybe need a second one for a stereo pair.  Thanks ACI for a great subwoofer
