I've been using my Dragonfly Red to drive my hifiman 4se for a couple of years (and my 4 massdrop model before the 4se). Recently the headphone jack has been cutting out on one or both channels. Re-positioning the phone connector helps momentarily, but the problem persists. So, my question is this: what is an effective way to clean the AQ headphone receptacle?
the jack mount and posts on the board are almost microscopic. I had no luck trying to re-solder.
Centrance offered me a small discount on a replacement but I had moved on anyway.
Thank you to all who replied. I cleaned the df red receptacle with deoxit, and that appears to have helped.
And- now I know how to open a df in case I need to service it further!
AQ Connectors are weak points in their products, IMO and experience.
I haven't heard a Dragonfly Red but I did own the Black version for a few weeks.
I was going to try the Red but then I read about the Sabaj DA2 so I thought I would try it. It sounded noticeably better than the Black so that is what I ended up with. I think I paid around $70 for the Sabaj and I have seen them going for less than that. It supposedly won't work well with an Android phone and it may use too much power to work well with older iPhones. I use it with my laptop, Grado RS-2's or Koss Porta Pro's and for a cheap headphone amp, I think it sounds good.
Sounds like a loose connection in the Dragonfly. Can likely be solved with a soldering iron.
Have you tested the headphones on another device to make sure it's the DF red?
I tested the headphones using the jack on my ipad, and the fault is with the dragonfly. It remains even after cleaning the dfly jack using a stripped down qtip moistened with a small drop of deoxit. It's a shame because the dfly red has been a very satisfying dac/amp.
Id send it back to audioquest....could be a break In the cable somewhere
Unfortunately, well out of warranty. This unit is at least 5 yrs old. I tried cleaning the receptacle using a stripped down q-tip and contact cleaner, to no avail. Time to retire the dragonfly, and find a replacement.
