All true but remember, if the CST1's sound as close to the N3Tl's as I've heard they do, you;re talking about a speaker that probably reaches at at least 3 x it's price point or more than 6x the price of the B5 !
I've said this numnerous times in the past, every time I hear the N3Tl's over at my folk's ploace, they bring a big smile to my face. They were my first GR build and I'm still impressed by them every time I hear them, the CST-1's have good roots
