I’ve never heard the German Physiks though I’d like to. Decades ago, I owned Ohm Fs which had serious shortcomings, but sounded incredibly musical. A bitch to drive and flabby in the bass, but the omnidirectional nature of the Walsh driver filled a room so differently than a box or planar driver. I’m guessing the GS Unicorns have no such deficiencies. 

Nicely done - enjoy!
