The darkvoice headphone amplifier I received has an issue that I’m curious about. I’m not sure if this is an intended feature or a problem. The very first time I tuned it on the blue power LED on the front panel began flickering, then turned off completely within less than a minute. I’ve cycled the power on and off several times and the light will sometimes come on for a few seconds before going out, almost as if once the amp is warmed up, the LED goes out. There does not seem to be any other problem with the unit- it sounds great actually. The manual is all in Chinese, so it’s not any help in looking into this issue. The main complaint many users have had in the past is the bright blue LED, so maybe a new feature? Anyone else experience this or know if this is a known issue, or an intentional feature? I’m actually fine with the LED not working, I just don’t want it to be a possible sign of an underlying problem with the amplifier itself that won’t reveal itself until later...
theJabberwockThat flickering started happening with mine about a month and a half in, and I have to agree, I'm totally fine with the LED not working, that thing was almost obnoxiously bright. The DV still sounds great, I haven't detected any problems so far. That being said, the flickering only started like a week ago so maybe not enough time has passed to detect any issues yet.
citrusfetishGood to know. Thanks for the reply. Massdrop doesn’t have any darkvoice amps available to exchange mine for, so I think I’ll keep this one. Hopefully it continues to work.
