The WeissKlang V13 and the KlangFormer were reviewed
by the well-known German audio magazine Professional Audio (07/2017) with the result:
VERY GOOD / OUTSTANDING
"...As an extra feature, Sonimus' KlangFormer plug-in allows you to discreetly but effectively alter the neutral WeissKlang sound with five different colorations."
We are very pleased and would like to thank Professional Audio ❤.
