Disturbd1 Posted May 18 Share Posted May 18 Build 957 Device model: Samsung Galaxy S22 Ultra Android v13 My USB DAC is a very capable one, from what I understand. I believe it is also capable of serving to provide a bit of amplification as well. That said, I'm noticing a recent deterioration in low-end frequencies when I use it in PA. For context, I'm using the DAC to power the JVC HA-SZ2000 headphone. If you know anything about these, you know they're renown for bass reproduction without breaking a sweat and without any artificial assistance. They're simply highly-capable drivers. For the life of me, I cannot figure out why the low-end has drastically deteriorated. I don't pretend to understand all of the settings in the PA audio and EQ arenas, but I've historically cranked the low-end and ensured hi-res output was used where feasible without issues here. When I'm not using the DAC (say, connecting BT headphones) I can sense a tangible change in the low-end as I increase/decrease the Bass knob or the EQ levels. The DAC is fairly new, having had it for less than 6 months at this point, so I do not believe there is an issue there. It certainly wouldn't surprise me to learn OneUI or Samsung in general are playing a role here, but if there is something I'm missing or not considering I'd like to find out. It's killing me having a fraction of the low end come through on these headphones that I know they're capable of (including with this DAC).
