Epiphany Acoustics E-DAC Review Thread

"ODAC + NECO V.3 + Sennheiser HD580 = A MATCH MADE IN HEAVEN.
I can't tell you how beautiful this rig sounds. We all know how well the HD580/600 scales with better sources and amps.. but synergy is often undervalued. The ODAC is beautifully resolving and clean.. but the Neco really steals the show, IMO."

"It's downright disturbing how incredible this combo sounds with the HE-500. In fact, it should probably be illegal (**looks at Arizona**).

AudioQuest Bumblebee Android DAC:
AUDIOQUEST BUMBLEBEE || AVLAND UK information, pictures & spec for the

"Designed specifically for Android devices
24-bit ESS Sabre conversion chip
Supports all music files including 24-bit/192kHz lossless
Drives headphones directly with 3.5mm mini-jack output
Fixed or Variable output modes
Asynchronous transfer for accurate digital timing
64-position (computer-controlled) analog volume control
Isolated dual master clocks
Colour changing LED to indicate source sample rate"

I am wondering if the AudioQuest Bumblebee Android DAC is a standard self-powered USB DAC or an Android-specific USB DAC.
Android phones and USB DACs

The AudioQuest Bumblebee should be likely an AudioQuest DragonFly with built-in rechargeable battery, because it "supports all music files including 24-bit/192kHz lossless".

AudioQuest DragonFly USB D/A converter | Stereophile.com

And an Android-specific USB DAC can support only 16-bit/44.1kHz:

If the AudioQuest Bumblebee is a standard USB DAC, while using with a PC or a Mac, the sound quality of the AudioQuest Bumblebee should be superior to the sound quality of the AudioQuest DragonFly thanks to a clean battery power.

Hello all,
I was directed to this thread to ask my question, and I hope someone here can help me out. I'm in the process of designing a way to dock our phones with our cars to not only stream audio, but also video. Android phones do this very well with hdmi, they just all do it differently. The GS3, like you all know, uses MHL, but not the normal 5 pin MHL, rather their 11 pin version. I'm sure there are many reasons why they used a new form factor. My question is, with the old 5 pin it would charge your phone at 500 mA, which isn't quite enough, and phones with the 5 pin mhl would slowly die. Is this different with the 11 pin? Does it charge at a higher rate? Do any of you have the new 11 pin mhl cable (not the 5-11 pin, rather just the 11 pin), and could you check this out for me real quick? I use the app below on my phone to check the rate that it charges at. Please let me know, this would really help me with my project. Thanks in advance.

About Android-specific USB audio:
"As of now, the standard Android releases do not include USB host support. Samsung decided to add this feature on their own. The Android folks are working on a funky USB dock protocol that works over USB (sort of like what Apple does) that, frankly, most of us developers think is stupid. There is certainly a push to put USB host support for standard devices (like audio, keyboards, etc.) into the normal Android releases."

The us$43 Samsung Galaxy S3 + Car Stereo Upgrade for WAaaY better sound quality!

Galaxy S3 > digital USB audio out >> "USB OTG" cable >> Behringer UCA202 USB DAC >> car stereo amp >> car stereo speakers

"...
And so what are the results you ask?

HOLY MOLY!
Not only is the audio quality MUCH improved, but the sound is so CLEAN now. No clicks, burps, or any other weird background noises. Just straight CD quality background silence.
Even my GPS voice sounds prettier. hahah
Bass is tighter and deeper. Highs are more revealing. Everything is so much better that a novice could tell it sounds better.

And yes, GPS navigation works perfectly. If I'm listening to Pandora or an MP3 and my GPS needs to talk, then my music will go several db quieter and GPS will speak up, then afterwards the music will automatically go back to full volume.

Also, one thing I hated about Bluetooth was everytime I turned my car off for just a minute, when I would power it back on the Bluetooth would not consistently reconnect. Well, this USB-OTG has been very consistent for me so far. Music just picks back up where it left off at and is fairly quick to do so.

Cons? Well, I haven't tested hands free calling yet. But I'm told it doesn't work with this USB-OTG to DAC configuration. Maybe there is a bluetooth solution for that. I dunno? And AOSP does not yet support DACs.

Pros? Freakin everything.

Pics are below.


Here is the DAC and the USB-OTG cable:

This is how you configure the DAC.
You can probably also use the headphones output instead of the stereo RCA, but I didn't try it.

I wired up my USB-OTG cable to my iBOLT dock. It comes up through my dash defrost vents.

This is what the three connectors on the USB-OTG cable look like:

Here is the DAC being wired up. I taped up the non-used RCA's to prevent anything bugging with them.

I wrapped up the DAC with DUCT tape.
Not sure how or why the pic is sideways. It looks normal on my desktop.

Hid it behind my dash.

Here is the USB-OTG cable with my iBOLT dock.

The car stereo w/audio cable attached. Some car stereos have the 3.5mm connector in the back. Or a dual-RCA input. I'd prefer one of those to have a cleaner install. Maybe someday I'll upgrade my car stereo.

And here is the finished product. My S3 docked, charging and outputing beautiful digital music!

For the record, using a otg cable and usb microphone (and a usb recording app) I have managed to turn my s3 into a high quality digital recorder. I use it to get interviews for a local radio station.
