I understand the merits of HT more then that of 2-ch. What Im saying is that speakers within the same family will be voiced more accordingly then speakers from other lines in order to create that seamless soundstage you're talking about.
I don't have to tell anyone that Contours don't sound like Focus speakers. The Esotar2 in the S25s and Sapphires don't sound like the 5.4s or C2s... so theres no way to assume that the esotar2 in the SCX will sound like an exact match to the 380s. Like I said, I heard the 380s and the 160s, they sounded identical from my recollection. The only true way to know is to listen to them both.
that said, will the SCX be a better center channel, Id say yes. It will sound bigger, have more impact, probably keep up with the 380s more easily, and have overall greater resolution, however will the transition from R/C/L sound seamless and completely correct? Or will the SCX center channel sound more contour like and be a little more laid-back?
