Beautiful! I am on the way to the 300B also. I just cannot afford it yet. I will probably begin with a pair of 2A3's from Bottlehead (Paramours monoblocks), and when I can afford the jump up go for a pair of Consonance Billie's (monoblocks also). The Billies have more power and more bass.Your speakers are beatutfil and I like the way you made them to fit the corner.
Questions
What are you using for the XO, is it the origonal?
Is the box sealed or ported?
thanks
