That is certainly a major point. The reasons I keep considering the DACport HD are two, output power (which obviously directly influences battery drain), and the separate volume control. Also I could get the DACport HD with a 40% discount...

Will a direct lightning to mini-USB work when connecting Opus 11 to an iPhone?

 

[s4tch]

bumping the thread with a quickie: this, or the xduoo xd-05? i prefer warmer sound signature, tight bass, i listen to rock, metal and jazz, and i'd pair the dac/amp with my android phone to drive my akg n40. any feedback is appreciated.

Phone Battery was draining fast

Started the phone
Started the OPUS by plugging in headphone...then connected both after both turned on.
Seems to have fixed that issue.

Interesting review. I have a less interesting question though. What is the case that you have for your Note?

 

[Paul Oorbeek]

I have an Oppo PM3 headphone and i just bought an second hand Ifi Nano IDSD how will the Audio Opus 11 compare with it soundwise? I will use both connected to my LG-V20 handphone.

 

[pinoyman]

Subscribing...

It's a Note 4

I can look for the item if you got a Note 4

Love the #11 BTW. Paired with my Note 4 is better than 2 of the 3 OPUS DAPS IMO

 

[bencherian]

Just a question here. LG G6 quad dac has Ess sabre chipset using and that too in quad dac version. Ess sabre 9028 i guess. How does it sound fare against this Opus 11 dac connected phone let's just say iPhone dor example

 

[Hawaiibadboy]

No idea. OPUS #11 is my 2nd favorite OPUS product only behind the #1 aluminum DAP.
Love the #11 smooth yet detail rich sound

 

[bencherian]

I am using G6 now and planning to change the phone to Mate 10 maybe.. But the audio will be a huge let down in that compared to G6.
Which portable dac should i use in order to get warmer sound... Ya i like warmer sound rather than brighter sound...
Audioquest dragon fly Red and Opus #11 are currently in my list.

I've never heard the Dragonfly red but for phone usage I'd strongly recommend getting a dac with internal battery.

 

[bencherian]

Means opus 11# has internal battery. Have you got any other options ? I dono much about these dacs . Budget friendly also preferred around 250$ .
Warm sound is what i like.

For phone usage the #11 is my favorite in that price range. It sports a very good combination of size, features, battery life and sound quality imo.

I guess i have to drop the idea of Opus #11 because i need a bit warmer sound. I don't like sharp sounds . It triggers my headache.
Can you suggest warm sounding dacs at same price point please?
