The ’57’s are some of the most coherent speakers I have ever heard in the mids to the lower treble. The ’63’s are not quite as coherent, but they are a little more extended in both frequency extremes, IMO. Stacked ’57’s are pretty amazing IF you can accommodate their requirements.
Now, here’s the thing, IMO and IME. Neither is a speaker that I would want for my primary system, too many limitations and restrictions with both. Many times, i contemplate a great pair of ’57’s in a secondary system...BUT as a secondary system only.
BTW, IF you go for either...a nice mid powered tube amp is the way to go...like an ARC D70Mk2 that I used to own. Match made in heaven.
