Some of the reviews of this amplifier as follows:
"Symasym absolutely incredible!
Prominent characteristics are the wide dynamics, resulting in a steady bass, deep, and powerful. And special reproductive detailed sound and detailed, without kolorasi sound. Staging her really three-dimensional. Bak enjoy incredible sound stage!
When amps in turn on / off ON / OFF does not cause strange noises like tuk or duk. Really clear silent.
His voice is pleasant enough, there is no excess or false treble, soft but very transparent. All types of music can be played quite nicely by Symasym. "
Friedrich Schmidt / Germany Cnet review:
"The struggle to assemble amplifier for days paid off. When Symasym connected to the soundcard. The voice sounded pure. No excess or less. No matter what kind of music entered into Symasym, always sounds incredible - felt warmer than transistor Symasym / Toshiba. One thing is certain: I GainClone raft before, just counting days to rest.
