OPPO HA-2 Portable Headphone Amplifier/DAC Discussion Thread

Does anyone know why 32bit is not showing up I believe it says on spec page 32bit on oppo website.

32-bit audio is pretty much nonexistent, if not nonexistent. Your computer will only go up to 24-bit on the settings; only with certain media players will it display 32-bit. The SABRE DAC itself operates on a 32-bit architecture for their digital volume control feature.

My friends Macbook shows 32bit option with the onboard sound.  So I know OS X has a option.  I'm not really understanding what the volume control has to do with 32bit.

That's probably 32-bit floating point, which isn't the same as 32-bit in the sense of 16/24/32-bit. At least that's what it says on my Retina MacBook Pro (OS X Mavericks).

The ESS SABRE DACs use 32-bit signal processing to handle digital volume control.

Oppo HA-2 or Beyerdynamic a200p??? I want to pair it with my iPhone 6 plus and MBA. Sound quality and wider sound stage are my biggest considerations. Any other recommendations will also be appreciated.

Hi. I have not heard the Beyer but have been comparing the Oppo to the much more expensive Chord Hugo, using an iPhone 6 as my source. The Oppo delivers a great soundstage with excellent depth and instrument separation at a fraction of the cost of the Hugo. I use ATH-ESW9s cans and RHA 10i iems and get superb results with each. Low gain seems to be Oppos best setting for optimising the soundstage according to the other reviews, so do consider that if you need high gain to drive your portable headphones. The Oppo has given me a superb boost in listening pleasure from the standard Apple compression files on my iPhone. Really excellent value for money, build quality, design and performance. You will not be disappointed with the Oppo in combination with your iPhone 6.

I believe the Beyerdynamic A200p has the same DAC as the IPhone. So there is no upgrade beside the Ampsection of the A200p.
I do have an Oppo-HA with my Iphone 5s and love it. Matches great with my IE80 and Shure SRH440. It also drives the Beyerdynamic T1, but not to its fullest potential.

A200p is the same as A&K AK10, running on a Wolfson WM8740, which should be better than the DAC inside iPhone. Though not nearly as good as the ES9018K2M inside HA-2.

Agreed.  NativeDSD.com has a handful of 32 bit/384 kHz WAV samples, known nominally as "DXD".  And yes, the Oppo HA-2 will play them.  But it's not like there's a market for 32 bit purchased
music out there.

DXD is just denotes 384 or 352.8 kHz sampling rates though. It was used to make a PCM equivalent of DSD such that engineers could manipulate the audio signal in a traditional PCM method but still have the resolution of a DSD recording. I have one DXD album from 2L, and it's 24/352.8. What's deceiving though is that the signals only go up to about 22 kHz in the spectrogram... I haven't purchased any DXD albums from NativeDSD, but I'm guessing they're 24-bit as well?

But yeah, DXD music is extremely rare and I almost never see it ever outside of NativeDSD and 2L. 32-bit recordings...I've never seen before and there's really no reason to use it. DSD256 is also extremely rare. The good thing is that even if they don't really exist now, DACs like the HA-2 will be a little more future-proof in that regard since it is able to play-back those files.

That's weird going juts up to 22Khz, like normal CD quality... my 24/96 go to 48KHz, and 441.Khz if they are 88.2 and my lonesome 192Khz goes yo 96K

For those of you looking for a more elegant solution for connecting your Sony Walkman device with your HA-2, we've been able to confirm that this cable will do the trick: http://www.amazon.com/dp/B00YWEHSQY
 
 
This cable works with the Sony Walkman NW-ZX1, NW-ZX2, NWZ-A17, NWZ-A15, and NW-F880 series.

If you where as smart as Fiio, you would offer something like this in your own shop. The lack of such a cable in the EU keeps me from buying the Oppo H2.
It is all about the connectors, st***d!

Mexico has 122.2 million people, the EU has 507.42 million people. The US has only 318.9 million people. If Oppo would create two shops one in Mexico and one in the EU for such cables and other stuff, they could increase their sales a lot. Maybe we should add Brazil to the mix, you can add another 202.7 million people. Maybe we can get those numbers to the Oppo management to change their mind. My country, Germany, is only that successfully because we sell always global. You might want to look at Sennheiser. Most Chinese companies are the same.

, they arribved 2 days before i left back to mexico.
 
didn't do it with malicious thinking that germans re as closed minded as americans, I did because to save on taxes and shipping fees ah and because i didn't want to fly for 15 hours with no music
