​and has someone compared them Sonic wise?
The new version is still pretty new but here's one comparison

I reviewed them earlier in this thread in two parts.

Here and here.

With Sabre DAC chips, the way they're implemented is crucial to how well they'll perform. Unfortunately, most companies do not implement them well and Oppo is no exception. The result is a mediocre DAC performance with what many describe as the Sabre glare.

I'm considering this dac/amp to go along with an iPhone but one of my problems with the iPhone is the lack of expandable storage. Belkin released this adapter that allows you to connect two lightening devices together http://www.apple.com/shop/product/HKKP2ZM/A/belkin-lightning-audio-charge-rockstar?afid=p238%7CsctLS451X-dm_mtid_1870765e38482_pcrid_52243358770_&cid=aos-us-kwgo-pla-btb-all-slid--product-HKKP2ZM/A

Has anyone tried that adapter along with a lightening memory stick?

Has anyone got their HA-2 to work with ViPER4Android on an Android phone?

Thanks very much.  Very good food for thought with regards to the quality of the headphones being something to target, consider in the mix.  I am a big home theater guy (although on a budget) and yeah you can get a nice 7.1 amp but if you speakers cost $100.00 for a 7.1 set... you are not going to be happy!  (exaggerated example obviously) :)

I'm trying to trim the fat. I have a Nuforce HDP that I rarely use, and I notice it only does 24/96 via USB. Is there anything I'm overlooking, and would regret if I sold it and just used my HA-2?
I have a few DSD and 192/24 albums and I rip my blu-rays with uncompressed audio streams, so the HA-2 wins for playback there. My most demanding headphones are 32ohm Denon D7000 so again the Oppo seems to be all I need. Any advice would be appreciated thanks.

Seems they are actually 25ohm

  anybody using the ha-2 with 1964 Adel series?  Are you getting any floor noise/hissing?
 
gonna pair the amp with a pm-3 and u8

With the SE846 there's definitely hiss... so if they're equally sensitive you'll get it too.

regarding the 1964 Audio Adel...

I have the bass emphasized A4 and it matches well with the HA-2. I do use the Apex M15 module. No hiss.

Does anyone have any idea as to whether the HA-2 is compatible and works with the Google Pixel?

I don't have a Pixel and so can't test it for you with the HA-2, but I see no reason why it wouldn't work as the Pixel ships with an included USB Type C OTG adapter, which they call a "Quick Switch Adapter" (because you can use it to migrate your data from another phone using that phone's standard charge/sync cable). This means the Pixel is OTG/USB Host mode compatible.
 
That included "Quick Switch Adapter" is simply a Type C OTG adapter, it's all you'd need to connect the Pixel's Type C port to the HA-2's USB input, using any existing good quality micro USB charge/sync cable you already have.
 
Not entirely clear to me however that the Pixel ships with that OTG adapter in all markets and with all carrier packages etc... so you'd need to confirm that or possibly end up needing to buy one separately.
