"The stasis circuit developed by Threshold, guarantor for load stable power supply in the low impedance power range, worked in the well-known power amplifiers, and in the flat receivers!
 
  
The SR-2,3 and 4 receivers, SR-4 remote controllable, had a good sounding phono section (the 2 unfortunately only MM) and of course an excellent tuner built in.
+
== Berichte ==
Soundwise these parts tend to a natural, rather deep and wide, than high stage. ... At the same time, the parts still look chic and are well adjustable, just no debris.<br />
 
Today, after more than 20 years, if you get your hands on a semi-maintained unit, they run flawlessly. A manufacturing quality that the Europeans and Americans were running after!"
