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.

Hello - I've read through the 1995 review a few times and I'm impressed with the engineering and performance of this DAC, but I've never heard one. Does anyone have an opinion about how this would compare sonically to modern DACs for only 16/44?

thank you

Dave
