The Andros Phonostage receives a "Class A" rating

          in Stereophile's annual Editor's Rate 500+ Top Audio Products issue. 

What does Class A mean? 
Stereophile defines Class A as "The best attainable sound for a component of its kind, almost without practical considerations; the least musical compromise. A Class A system is one for which you don't have to make a leap of faith to believe you're hearing the real thing."
 
Michael Fremer, Analog Corner Editor for Stereophile magazine quotes,
"The Zesto had an addictive, warm overall sound, with plenty of impact, detail and grace. It's among the more enjoyable and satisfying phono preamplifiers I've auditioned at any price."
