The almost new DAC by JADIS: JS1 MK4 USB

Hello folks i wonder if some of you have the chance to listen to this new gear by JADIS, the JS1 MK4. Comparing the internal from pictures of the new one to the first version it seem that the power supply and also the dac section have been modified heavily (upgraded ?). So i want to now about the sonic differences or improvement coming from the evolution to the MK4 ? Still liquid, warm and lush sounding ?
