Just picked up my new HA-2 (10 percent off from for my local dealer's nearly new audition unit)

for android usage and the harder to drive HE-500, I would definitely personally recommend the HA-2 over the AQ dragonfly.

the AQ dragonfly is more at home being used with a PC/laptop with its usb stick design. AQ dragonfly also doesn't give any amplifier power ratings, so not sure if it would be adequate for the HE-500.



I've read somewhere that HA-2 sounds digital... is this true?

Since a number of people reached out to me after my HA-2 review asking about 30pin iDevice support, here is an official answer from Oppo regarding this subject:
 
Quote:
 
only the last models to use that connector tend to work:
 
iPod Classic 6th and 7th gen will work (model A138). Previous models do not work.
 
iPod Touch 3rd gen (model A1318) and 4th gen (model A1367) both work

 
Considering A-port with full USB connector is dedicated to Apple support, if you have models listed above would be great if anybody can test it with their usb/30pin cable and get back with a reply and confirmation.

not to my ears. Perhaps from a warmer sounding dac background, they may seem brighter, but I consider the HA-2 to be quite neutral.
 
Dragonfly & Herus are relatively 'brighter' and 'sharper' sounding dacs.

Any tips on ergonomics? I have an iPhone 6 plus which is a bit awkward to have the straps attached all the time. Should I bite the bullet and get an iPod touch? Looking to use with the Qobuz app

I'll show you what we've done with a (similar) rig. You need to buy a hard case, one your iPhone snaps in / out of then attach the case to your HA-2 (we used some 3M double sided tape) Keep in mind with HA-2's finish you want something which won't permanently mark the dac/amp body.
 

 
Using the hardcase allows you to remove your iPhone out anytime you're not using it.

Hey Money,
I think that you did a bit of translation there. I wanted to comment, but could not really grasp what the OP meant when he referred to the HA-2 sounding "digital". Should the interpretation mean sharp and/or bright? Not knowing what he meant, I translated to sounding mechanical or processed. Sort of like what people said about CDs versus vinyl. A hard thing to put into words... but in none of the interpretations familiar to me did I find a description of the HA-2.
