Hello. I have owned an UP4, paired with Samsung S10.
Is it normal that:
- using as USB DAC is it much quieter than my Hidizs S3 in all configurations - low gain, high gain, dual dac, 3,5 mm, 2,5 mm (and max volume is even for 2,5 and 3,5);
- using with 2,5 mm balanced headphones dual dac option is not available (in BT and USB mode);
- using as BT DAC with LDAC codec is a WAY LOUDER that Hidizis;
- using as USB DAC only volume control and mode button are working (clicking on wheel button does nothing);
- using as USB DAC Shanling Controller did not recognize UP4.
I am using Final Audio E5000 with 93dB/mW and 14 Ω.
