Souphero, the restored Scintillas will sound almost just like the older ones on any amp capable of running well at 1 ohm, and that is a precious few. A lot of folks are enjoying them. With say, a Krell, the top gains a bit of pepper. That's nice for a sleepy class A amp.
With my amps, the salsa on top turns into tobasco. Any instrument with a sharp report was a painful listen. Zakir Hussain playing his tabla sounded all the like of lead pipes smacking each other.
It has nothing to do with, "Tired ribbons," a retort I hear too often. Henry Ho has freshly ribboned Scintillas, only with natural Apogee ribbons. His sound like mine.
