  Do you guys think that OPO needs Viper4Android instead of AudioFX (Pre-installed).??
Since I am using Sony Xperia P, and due to its support ended at 4.1.2, I installed unofficial CM11 into it and then I started missing the Sony Walkman and its MusicFX.
 
Then V4A comes into my story and after a whole day of tweaking, I actually managed to get a sound, which I never get out of my PC.. xD
Em owing ATH-M40x and alot of people over here says that after using M40x & M50x, M40x have a flat response and less bass as compared to M50x.
 
But after driving by V4A, they get magically converted into ATH-M40x cum Beats by Dre. The bass is too gud with distortion.. Perfect mids and Low. Flawless Highs. Love the sound on Xperia P.
 
So, Do u think I shud get the V4A for OPO too.. I just ordered my OPO and Its in SnS Stations, so it will delivered to my country in just 1 week or so. Actually OnePlus doesn't deliver it to India currently..

I just loaded V4A last night on my OPO; seems to work well so far, i can't comment on audio difference yet as I haven't had a chance to sit in a quiet area and compare.

Done, and thanks.  Your findings are listed here.

Just had a look at your page,the OPO works with the Stoner Acoustics UD120 DAC with  and without UAPP.
Although Ive still to come across a better sounding player than UAPP.

*update* on my JDS Labs C5D.   
 
OnePlusOne---usb-otg--->C5D-->Shure s846-cl.
 
Connects nicely, and sounds good.  After ~30 minutes; sound gets 'fluttery'.  Seems to be as the phone warms up; I hear almost a sharp single tone shadow of the currently playing music..  The longer I let it play; the more often you hear it.  Really takes you out of the music.  I *only* hear it with my s8s.    If I plug anything else it it sounds as expected. (The sensitivity?).  USB components of the phone warming somehow maybe?  If i plug via separate cable into my laptop; an hour or more of DAC+AMP usage doesn't reproduce; only out of my OPO via usb to the c5d after ~20 minutes of warmup(If i give me a few minutes of break; it appears again much sooner once I begin playing again)...
 
 
I also don't hear the noise when I hook up the c5d via mini-to-mini cable and use purely as an AMP, or if I less sensitive headphones on the C5D., or when I hook the C5D up to my MBP via usb.  I also installed V4A on the phone, and placed it in airplane mode with the same results. 
 
The only two things I don't have the ability to isolate being USB on the phone and the USB-OTG cable; I would guess the phone being much more likely the culprit..    C5 as an amp isn't much of an improvement vs using the headphone jack straight that I can tell(both sounds good); but using it as a DAC+AMP is a noticeable improvement.  Darn

  How's the SQ of 1+1 when pitted against your Vivo Xplay 3S?

Sold the Xplay, but the Vivo was noticeably better.
 
However, it could only engage the DAC/Amp in the Vivo music and movie app. Didn't work outside of it.

This is all useful information, worminator; thanks for posting about the DAC/Amp I'd been considering as a next purchase.  I'll add your findings to the DAC list on XDA before or over the weekend.

I appreciate your letting me ken, cattlethief.  I'll revise that entry on the list.

Any of you have an invite? Not slept for days in my hunt but to no avail 

 

[Poimandres]

I think invites are done until after the pre-order

 

[Poimandres]

I will say that feeding the glacier via USB sounds phenomenal. Even though I have the mobile networks turned off I still get interference through the glacier from the WiFi when the glacier is stacked below the opo and thus I need to turn on airplane mode. Problem solved.

BTW the only reason I bought the opo was for portable streaming to the glacier. I only wish it was a little smaller to match the glaciers footprint. If I could put the opo on the Verizon network I would likely buy another.

 

[fihidelity]

Well I did preorder but there's an option to use an invite to skip the 4-6 week wait which I'm all for! 

 

[elcubano1]

Hello everyone, I just pre ordered the OPO two days ago and got an estimated ship date of 4-5 weeks.
Can someone kindly pass an invite my way to help skip queue?

Great thread btw.

 

[Dimitris]

Hi guys. I am looking for a bigger phone than my iphone 5 and this seems to fit the bill. Does anyone have an invite for me? Please PM if you do.
 
Thanks!
Dimitris

Is it just me or is the headphone out super sibilant? I'm not particularly sensitive towards it but even I notice it a lot.

 

[cattlethief]

Ive got a spare invite if anyone wants it,goes bust in about 20 hrs.

 

[Enigma87]

[cattlethief]
