I think these guys are giving you good advice. Me personally I have no interest in the 321. Since I already own a 112, my only argument is whether to get a 127 and sell my 112 G and I only I can make that decision. In your case assuming you don't own a base, to me, the 372 is a no briner. The 424 is a nice piece and I honestly am on a list for the 425. I decided I liked the cleaner more base characteristics of the 424 just ever so slightly over the 425 or 448/449. I also would suggest take a long hard look at the 232 in terms of rads, it's my favorite rad and they are an SE. But with that array, to me it's the 372.
