The standard, all-in-one O2+ODAC requires A/C power, doesn't it?
 
The JDS Labs integrated version has the batteries removed and this is the place where the ODAC resides.

I believe even nwavguy himself would admit that HE6 is one of those rare headphones that O2 just simply won't power well enough.

I don't see why it wouldn't have enough current for the HE-6.

Looking forward to hearing the ODAC+O2 combo!

Yes, that is correct, only some custom builds keep the batteries.

Read his "More Power?" (September 2011) and "O2 Headphone Amp" (July 2011) articles, and the HE-6 measurements at InnerFidelity. From these, it can be estimated that the O2 on AC power would be capable of about 105 dB maximum SPL driving the HE-6 with correctly set gain. Therefore, his opinion would likely be that the O2 is sufficient for those who listen only to music with limited dynamic range (pop etc.), and/or not at high volume, but clearly not for everyone.

105dB is more than enough for me o.o
I usually listen around 80dB...

 

[stv014]

It is 105 dB peaks, though. If you measured the 80 dB with an SPL meter, then it is probably an averaged value, and possibly A-weighted as well.

Me too! He hasn't updated his blog in 4-5 months and I am starting to get antsy.

Thats why I decided to integrate my own and now with several o2's i have several cans in each to compare.

Recently it even takes weeks for comments to get approved, so it does not look like the ODA will be available soon.

 

[adydula]

But even if the ODA never comes out, you still can get the world class performance at this price point "now"....I wanted to wait as well for the 1/4 phone jack and RCA connectors etc....
 
But its such a low cost for what it does....why wait...I modified my ODAC's to fit my systems and arrangements...added RCA's etc...
 
Its not that hard and you can find people to do this for you...
 
The ODA specs etc will be great I am sure....but I dont think it will be even close to an order of magnitude....
 
Enjoy now....

This or the new Alo Audio Pan Am. I'm not convinced that the pan am or any other amp worth $300 or up necessarily has better sonic quality. Then again I've never heard a $300 or up amp, only my Fiio e17

Price is not necessarily a good predictor of headphone amplifier quality. You don't "get what you pay for" if the phrase means "it costs more, so it's better."
 
My Matrix M-Stage doesn't produce better-sounding audio than my FIIO E5. The E5 is much smaller and runs from USB power. The M-Stage has more gain and more power. That makes each of them better than the other.

This just can't be my imagination but the USB cable that comes with the O2+ODAC has a ferrite and I believe the ferrite filters the high frequencies. When I changed the USB (ferrite-less) cable, the high frequency came back. At least to my ears. The treble is much better, not recessed as before and the bass has more snap, punch, do to the restoration of the treble balance. Is it just me?

The phenomenon you're describing is an analog phenomenon; that's not how we detect problem with digital-audio output. If USB communication to the ODAC is marginal or failing, the result won't be enhanced or attenuated frequencies: We'll probably hear noise (e.g, clicking and popping.)
