They still exist. Their products are well built, although the older ones use a lot of parts now unavailable. So take care in case of repair. But I don't know any owner of a Spectral unit with a single problem.
And they're beautiful. Like old Goldmund gear when it was french or during their first swiss years.

converter as vivid and exciting - the class of its field

(at the time I was selling converters that competed directly with it)

I worked at a dealer that sold these too. Spectacular, beautifully made top of class component. At one point we were back-ordered nearly a year despite Spectral's regular production. Would love to see the reprint of the Spectral/ Avalon/ MIT system that was positively reviewed. After hearing Spectral at the store and at CES it's hard to want anything else.
Thanks for reposting this.
