About Sweetspot Audio
Sweetspot Audio is a sole proprietorship founded in 2009 by Sascha Symanowski in Lilienthal, specialising in the optimisation (tuning) and restoration of HiFi and home cinema electronics. The so-called Sweetspot Audio modification improves the sound quality and durability of devices such as CD players, streamers, DA converters, tuners, preamplifiers, power amplifiers and integrated amplifiers through the targeted use of high-quality components and proven circuit modifications; the company grants a five-year warranty on modified devices. In addition, restored classic devices such as the Burmester 916 or Transrotor Rotary are offered, as well as new high-end components, among other things as an official dealer for Viablue products. For the development, testing and comparison of devices, Sweetspot Audio maintains a 34 m² reference listening room with acoustic treatments and reference electronics. Demonstrations and device handovers take place exclusively by appointment, and shipping within Germany is free of charge.
