I received the Gungnir and Loki DACs this past Saturday. Switching between DACs is cumbersome and sometimes requires a reboot of RPi.
The sound just after half a day of listening is stunning, specially with the Gungnir. The DACs are listed as “Device” and “Device_1” in Volumio settings.
I once found switching from Gungnir to Loki that “Device_1” was missing, so a RPi reboot was required.
I do get pops and click with high resolution files, especially DSD files. (Pops and click with Teac UD-501 as well.)
Funny thing is, it’s so smooth that the pops and clicks sound like a record.
Doesn’t sound digital when using Loki DSD DAC. The output is less than great with the Loki, but it has to be expect with Op Amps and USB power.
I read a review where the reviewer used and external USB power supply for the Loki, but the power supply cost more than the Loki itself.
The HW/SW combination works, but some small issues. The Gungnir sort of shames the UD-501 as a PCM type DAC, but the Teac 501 is all-in-one, and the DSD sounds slightly better; is recognized by Volumio straight away. There is a big convenience factor with the UD-501. It also has a display screen, with some might believe is a noise draw back, but also very convenient. Gungnir has no screen, but I don’t really miss it.
In the UD-501’s defense, it has Op amp outputs. Gungnir uses discrete jfets outputs. Maybe an upgrade of discrete op amps would better the UD-501, if there is space in the case.
Any suggestions in removing pops and clicks in RPi / Volumio hi-rez setup? I tried the setting in System, and Playback, but with little change, if any.
