I have been a German Physiks satisfied owner for the last 15 years and due to my corporate career I had 5 residences in the US, Europe and the Middle East, thus I owned multiple pairs. I just retired and have consolidated everything in the US. I believe that German Physiks are unique designs and the people that own them, many musicians and conductors as well, keep them for life. For most people is a destination speaker. I have made some videos on my YouTube channel to provide an idea on their sound. Please use headphones for better results. I am currently in discussion with German Physiks to become their distributor in the US. If you are in Dallas, I will be happy to have a coffee with you and listen to music.
In the links below I have recorded some tracks on the PQS-302 and HRS-120 with two different set ups. The first with Ypsilon Electronics Phaethon integrated amplifier and the second with German Physiks' own Emperor Stereo Power amplifier. Phaethon is a hybrid amp and the German Physiks is SS. They also play well with tubes provided the amp is stable at 2.5-4 Ohm load.

Soon I will put videos for the German Physiks Unicorn, a horn-loaded, single driver omnidirectional speaker, and the HRS-130.
All recordings are done in my listening room with an iPhone 13 from the listening position.
Enjoy.
