New Juli@ Ex sound card has a significant defect that doesn't correspond to professional-grade equipment. I purchased the Juli@ Ex sound card from Thomann twice. Both times, I had to return the product due to the same defect. The output circuits contain a harmful, generated tone signal, the frequency of which changes when switching the sampling rate. It is present in both balanced and unbalanced modes. When monitoring is enabled, the level of this harmful signal increases. This signal is an aliasing of the frequency of the sound card's internal oscillator. This is a fundamental and unacceptable defect of the sound card. Requests to technical support regarding this matter remained unanswered.
Secondly, after changing the sampling rate in manual mode, the master output volume is reset to maximum, regardless of the volume control setting.
Thirdly, the analog inputs of the new Juli@ Ex sound card are 3 dB noisier than the inputs of the old Juli@ PCI sound card.
It would seem that upgrading to a more advanced ADC and DAC would have significantly improved sound quality compared to the old Juli@ PCI sound card, but alas, this didn't happen; it only got worse. The sound card Juli@ Ex has degraded, both in its component base and in the design of the circuit board. Even the packaging have deteriorated significantly. Overall, the new Juli@ Ex sound card is a complete disappointment and a disaster compared to the old, super-high-quality Juli@ PCI sound card of its time.
