Glad everyone is enjoying their Oppos. What phones (mobiles/handys, etc.) is everyone using, and which headphones?

I love the device, but it's unfortunately a little dodgy with some Android phones, such as my HTC One M8.

I use mine with Sony Xperia Z3 and Alclair RSM Quad. To my ears it sounds best with high gain. Like music has more dynamics. Don't understand it.

$299 + $35 in shipping from a trusted ebay seller

And package was marked with $25 usb sound card, so no toll / fee

Seller is called "BigBargainOnline"

He even threw in a genuine leather holster for it for no cost extra. Branded Oppo - same leather as wrapped around the unit.

I was worried about buying it from ebay because of fake products, but this seller is legit.

One thing though - because it is from China, the charger plug will not fit in eu, so you will need an adapter for that. No biggie, but worth mentioning

any of you guys heard the ADL X1? how does that compare to the Oppo Ha-2? (let's take out of the discussion that the Oppo looks 10000x cooler, and just focus on the sound)

Never heard of the ADL X1 actually. i think the design was awesome on that as well!

Sounds better on 32 bit rather than 24 or 16 bit.
 
Mine is only 32/192khz .
 
Music comes alive better definition sounds better really, goes well with high gain setting.
 
Mainly a bigger audio extension into the audio window that's all.

Hows the noise floor on ultra sensitivie IEMs? (8 ohms)

The issue is that sometimes the phone recognizes the Oppo, and sometimes it doesn't. I'm using that very nice short right-angle cable from eBay that everyone loves.

I'm running Android 5.0.2.

The unit used to pop and crackle, but that was resolved when I started putting the phone into "High Performance Mode."

Oh, I think we may have crossed paths before re the "high performance mode" as that was going to be my suggestion. I always turn my oppo on 1st then the phone and have had no issues. Mind you I mainly use my old Galaxy S3 when paired with the oppo.
 
Edit: I would suggest you head on over to XDA Forums and ask there;

Yes, high performance mode fixed one of the issues, so I'm thankful for your input.

I'll check out the Android forum; thanks for the suggestion. This will be helpful for when I purchase an Android tablet. I expect I'll have to do just as much research to ensure the devices work seamlessly.

Link to cable?

 

[shuto77]

Hi, this cable came highly recommended, and I don't think it's the weak link in the chain, since I also have this issue with the stock cable.

Just received my HA-2, thanks Amazon Logistic for keeping their promise despite many bad comments bout them (I was extremely worried lol).
 
Paired up with RHA-MA750i IEM, I'm surprised how different the same source and same pair of earphone can sound with without DAC/AMP. As this is my first DAC/AMP, I would say I'm rather pleased, and know why people can fork out such an amount for DAC/AMP. (My most expensive headphone being the NAD HP50, which is cheaper than the HA-2).
 
After some time of plugging in and plugging out my earphone from HA-2 to Mac and Mac to HA-2, I came with this first impression.
Soundstage is noticeably bigger, more of a 3 dimensional soundstage (depth, width, height) than just width and height without depth. Chester's vocal in Linkin Park's In The End sound further.
 
I notice better detail processing through the HA-2 too. In short, the sound is more 'open' now.
 
Will try it with my HP50 soon. 
 
Overall I am very satisfied with this product. Like what I was told, without DAC/AMP, there are layers of blankets and sheets around a set of speaker, and a DAC/AMP do help removing the layers in between, result in a cleaner sound.
