    Sabaj A10h Review (Headphone Amplifier)

    The case is metallic, but the front seems to be plastic only (I didn't disassemble it). I get interference when I just put the phone close to the headphone cable (phone >1m from the amp), so maybe there is something silly happening with the grounding. Sabaj's power supply is Class II with...

    AIYIMA A07 TPA3255 Review (Amplifier)

In Linux pavucontrol I see it's switching off/on about five times a sec, and I get "Unable to get default sink" errors. I ordered Topping E30 to remedy the...
