You're welcome. The case is a cosmetic enclosure that at the headphone end has a cap which is compressed and glued into place. It's possible that it wasn't fully inserted when assembled. Please stay in touch if you need anything.    Steve 

Hello Kammex –    Sorry for this. Have you contacted us directly at info@audioquest.com ? If this is out of spec we can work with you to make sure the product gets exchanged (if need be).    Regards,    Steve Silberman AudioQuest 

You make interesting points.   On the other hand brands such as Beats, Bose and Sony, while not what you/we may consider "high-end" still cost a considerable amount of money. So, that's a reflection of value by the owner of those headphones. A person who decides to spend 500.00 on Beats or...

Hi Defbear --    The reason that the "collective DAC sellers" have not gotten on this is that it is not a defect on the part of the DAC manufacturers. There is an inherent issue inside of Android's OS. What UAPP does is circumvent Android's audio system. So, there are two ways that the issue...

Hi Squish -    Implementation of the DAC is still a large factor. Things such as the power supplies, ground schemes, clocking, etc ... are also important. In the end, if the Red doesn't sound better than the V10 on its own you should feel entitled to return the Red. Our hope and assumption is...

Hi Mike -    The reason the Black sounds louder at a particular volume setting, such as when both DAC's are set to -39db, is because the Black's volume control doesn't track in linear (1db) steps. However, the Red does in fact track in 1db linear steps. As you move closer to unity gain there...

Hello everyone —   Thanks for your patience. There are several general questions and an overall concern regarding Android. I’ll address general questions and concerns first and save Android for last.   How many milliwatts do the DragonFlys output at 600ohm? DragonFly Red is capable of a...

Hello All –   First, we'd like to thank everyone one who's made the decision to purchase any of our products. we really appreciate all of the support. I'd also like to give a shout-out to Canali – he brought this thread to our attention.    Those of us who can thoughtfully jump in and answer...

Bmac-   condescension is always the best give away that a nerve has been struck.   Synchronous and Adaptive do not refer to the same thing. Are you confusing the terms Centrance currently sells an adaptive kit. When they started out they sold a synchronous kit. See the below definitions...

Dear Bmac-   You're completely incorrect. You need to get your facts correct.   Bianci, you are aware that the synchronous USB protocol that Mr. Goodman developed for Centrance is licensed to other manufacturers and is used in some well respected (and measuring) DAC's, right?  ...

Mr. Goodman,   I guess the question is this-. what implementation is better, Asynchronous or Adaptive? If you could figure out the code to Asynchronous would you be using it? If Gordon Rankin or DCS were offering you a license would you take it? Or, do you stand behind Adaptive as a superior...

  if you divide 12MHz by 44.1kHz you get 11.2896...MHz. So why bother using synchronous when the clock rate vs the standard sampling rate of 44.1kHz are not mathematically compatible? 48Khz is nice and tidy for synchronous but why bother implementing this format if...

Hello Bmac-   To quote the Well Tempered Computer..." Synchronous The clock is directly derived from the 1 kHz frame rate. There is a PLL that takes in the start of frame signal and generates a clock. Using this scheme its rather difficult to generate 44.1, but very easy to generate 48...

I've been reading Mr. Goodman's responses and boy are there some holes in his argument.   In practice, Asynchronous does not offer a significantly easier or cheaper clean up experience. Our DAC is cheaper than some asynch implementations and yet is sounds better in many respects, so it's not...

There seems to be a bit of confusion-   Gordon Rankin didn't invent asynchronous USB, nor has ever claimed to have. Asynchronous USB was invented by the USB steering group. You can find this at USB.ORG   http://www.usb.org/developers/devclass_docs/usbdi10.pdf   Gordon was just the...
