Brief Odac impressions
Dec 14, 2013 at 4:49 PM Post #1,771 of 2,018
Well, the voltage difference is huge, I'm running the wm8716 with no output stage (direct out) which with 5V supply produces humlbe 1V RMS of output, while ODAc has 2V as in redbook standard. I couldnt do a quick switch because every time I had to adjust the volme by ear to hear anything in one casae, or not to blow my ears in the other. Still, the DACs were very close if not identical, and that's surprising cinsidering that wm8716 was never meant for any ambitious audiophile stuff.
 
It's probably due to the amp and cans being not resolving enough but then again what gear is needed to discern sources that should clearly vary in quality.
 
People tend to put much too much importance on source disregarding upstream equipment.

Quick Question: I've done some reading on the ODAC vs. Dragonfly. Based on DAC only (especially since they have the same internal chip), comments seem to find them very comparable but that the Dragonfly was not worth the increased cost. But now that the Dragonfly version 1 has come down to $100 is there a compelling reason to spend more for the ODAC?

Nah, I'd destroy six ODACs trying to assemble one myself... not too cost effective.

Ha, I just saw this:

RCA issue solved!

Anyone who used the ODAC with an Android phone (no powerbank with pigtail cable or USB isolator), is the sound the same with a standard USB output from a computer? I'm just thinking maybe the SGS3 might not supply the same kind of power that a computer's USB port does. I have the Cantate.2 now but its own PSU powers the DAC circuit (the phone only powers the indicator lamp for the USB input), so I'm not sure if the ODAC is getting all the power it needs. I'll be using the RCA output version with the Cantate.

I used it with a Galaxy Note II and a Nexus 10. Worked flawlessly and sounded as good as from my iMac. I had a custom O2+ODAC powered on batteries. The ODAC doesn't pull juice from the batteries though.

Thanks! Is it safe to assume the S3 should be able to give it the same amount of power? Does using the ODAC with the Note 3 drain your battery a lot faster?
