A voice from overseas
Gear in my own system designed and built in the US - to the best of my knowledge:
Zu
Well Tempered Lab
Purist Audio Design
Synergistic Research
VooDoo Cable
Silent Running Audio
+ PS Audio, that until now I thought was also built in the US but Oddiofyl just taught me differently
The above is combined with units designed in Germany, US, UK, Netherlands, France, Italy, Japan, Poland, Canada, Belgium, Lithuania, Czech, former USSR, this includes rolled tubes and all tweaks in 2 systems + 1 in the making. Built in... not always shure.
