Overall the sound of this little thing is pretty good. Detail retrieval is excellent but I have noticed a bit of a digital glare to the sound. Vocals can sound a little shouty too. I think it's a decent enough little product and is priced sensibly for what it is - but I don't think it's a giant killer likely to compete with Mojo or higher end DAPs

 I have a 24/192 Vinyl rip of the DSotM  "Harvest Edition" (You o.k. with Pink Floyd?) I will upload it so you can tell me exactly which part of what song....like a :30 second run which demonstrates audibly the difference between the #11 and the way waaaaay over hyped Mojo. I owned that thing twice and compared them with some EX1000 IEM.
 
Help me help myself.

Even though my cable started working it now cits oit after a few minutes of play. Going to contact retailer for a replacememt.
 
Also a bit disappointed with lack of power when using apps such as Spotidy, Sky Go and Netflix.  Volume needs to be at almost full whack and even then its not even loud. Mixed results with Usb players such as Neutron, Hiby and Usb audio pro.

Nevermind, I wasn't able to reproduce this today. I must have been dreaming (or drunk)

I sent mine back to the shop. To be fair it sounded really good with my Trinity Audio Vyrus but I don't think it cut the mustard with my customs.

Definitely not a bad product or anything. Just isn't my cup of tea signature wise. Sounds a tad bright and artificial to my ears.

FYI if people are interested in using 3rd party cables with the Audio Opus #11, it's totally possible.

3rd party cables work by default, but I've found that the phone charges the DAC with these cables. Not ideal, you'll drain fast.

Using the supplied cable of course causes no issues.

If you want to use a 3rd party OTG cable, just do a mod and cut the 5v wire on the cable. Presto, cable no longer drains the phone battery!

FiiO otg cables (for their DAPs) also work (they actually seem identical as far as I can tell).

can opus #11 connected in iphone 4s ?
am curious about that.

Does anyone know if this can improve the sound of Spotify via an Android phone?
I've got a Samsung Note 3 and I'm using AKG K550 MKII and Ultimate Ears triple-fi headphones.
 
So far :
 
Audioquest Dragonfly Black - lower sound quality and volume than using headphone output direct.
Audioquest Dragonfly Red - dreaded low volume issue. No sign of firmware fix yet.
Chord Mojo - tried different cables in store, just couldn't get it to work.
 
I've got USB Audio Pro Player, but it's Spotify that I listen to most.
 
Would I be better off just getting an external amp like the Cayin C5 and give up on getting around the Android limitations/upsampling issues?
 
Cheers.

Am using on a oneplus and sound improves dramatically on Spotify with the Audio-Opus #11.

I think, from your description, the way you're thinking about android DAC/amp combos might need to change a bit.

Spotify will use the generic phone driver to interface with the Audio-Opus (as it would with any external DAC/Amp combo). Neutron / USB pro uses a direct driver, which is why those apps are recommended by theBit.

How good Spotify sounds depends on how good your generic driver is. On the Oneplus the driver recently improved quite a bit, meaning sound through Spotify also improved as the system generically interfaces with external DACs better without specialist players like neutron.

Now, i am not sure how much effort Samsung is putting into their generic OTG driver for audio output. I suspect not a lot, which is why you're getting sound quality issues and the phone needs a bit of help (USB Player pro/Neutron/Onkyo Player) to talk to the Audio Opus #11 or any external DAC/Amp. Which is probably the root cause of your issue with the Mojo as well.

BTW: this thing is freakin amazing. I mean I've previously used portable amps and DACs. But only with the Audio Opus #11 can I have beautifully tuned audio, Velcro to the back of the phone, and always have on me. Try doing that with a freakin Mojo.

Hi,
 
Thanks for the info and feedback of your personal experience.
 
I'm pleased with the overall sound of the Samsung Note 3, but I would like extra volume headroom (if I ever get the money to pursue more expensive inefficient headphones) and always would like better sound quality.
 
My current understanding of Android + Spotify was that Android automatically up samples signals, thereby causing a downgrade in sound quality using an external DAC/amp as opposed to UAPP which plays files using their native sampling rate. That's why I was thinking of just using an amp to avoid this extra conversion step. Maybe I've got that all wrong.
 
I'm going to give the Opus #11 a try at least. The only stockist I can place in the UK I can see is hifiheadphones. Is that where you got yours from?

Nice review. Great to see comparisons with some similar kit in other categories.

And I was actually wondering how it compared to the geekout v2. Didn't think i'd see that comparison without having to buy both. Thanks

I'm with Tony on this. I had the same experience with brightness and ended up sending it back.
Who knows, maybe we British prefer a different sound profile?

Thanks! I really like them both and they're also quite different sounding so personal preference will play a big part here (as always).

That's the impression I got. Also, great to see them photographed next to each other. Opus looks more portable, but did think they were comparable in size. Just nice to see an actual photo.
