Would be interested if Oppo hadn’t made the mistake of incorporating Thunderbolt, which is dying a miserable death due to non-adoption by the general public. Out of dozens of techies and audiophiles I know, not a one uses Thunderbolt.

Except it doesn’t use Thunderbolt. It’s a USB DAC. It includes a MicroUSB to USB cable for Android devices, and a Lightning to USB cable for iOS devices. There isn’t a Thunderbolt port, or included cable, on the unit.

I clearly misread something. Again, from the top. . .

I’ve seen said elsewhere that it is not practical to use whilst listenting on the move. Comment was made regarding cables. Do you feel this is the case?

I have also written about the HA-2 for another site and made the observation that if you are a pocket user, you won’t get the HA-2 and your source safely into your pocket without stressing the plugs/jacks on the units and cables.

If you have a purse, good on ya. Or, as Stephen mentioned, using it at a desk is about as comfortably and safetly portable as you can get with one of these front-and-rear-connected devices.

BTW: Good work, Stephen.

Personally, I do not often walk around with headphones on. Primarily I am at my desk at home or the office when listening. For me and my iphone 6 plus, which is already a burden to carry, having the HA-2 in my pocket as well would be too much. I don’t keep a nice headphone amp at work, so the portability of the HA-2 is great, allows me to carry it back and forth each day.

Stephen, What a well-written article this was! Really enjoyed reading it and bookmarked it too. I thought the way you explained the ups & downs of using the HA-2 (and also NOT using it) were perfectly worded and very clear. Now I have a great reference to use when explaining this stuff to people, at least regarding why one SHOULD use a portable amp/DAC instead of listening straight from their smartphone. I have just purchased the Celsius Sound Companion One amp/DAC, and I truly LOVE it! Have you had a chance to use it? Several reviews have said it trumps… Read more »

Stephen Hornbrook

Thanks very much. I haven’t tried the Celsius, but it does look good on paper. I can see about getting a review sample in.

I had to power cycle or input cycle the HA-2 only a few times and I haven’t noticed it happening for awhile, so perhaps it was a Windows/driver issue that an update fixed somewhere along the way.

RockStar2005

No problem. YW! Yeah you should write an article on the Celsus (sorry, I mistyped it as Celsius earlier) Sound Companion One. I would be most interested to read about it. I’ve seen at least one review say the HA-2 was at least better than Sony’s NWZ-ZX1, which costs almost double the price too (like the CO). So it does seem like a strong contender. Oh ok, that’s awesome! Did you do the update on it or was that something they did for the final release version of the HA-2? Sounded like a drag, so I’m glad they took care… Read more »

Hey Stephen,

I ended up switching to the Oppo HA-2 for various reasons, and I just posted a review on Head-Fi about it as well. I welcome you to check it out……… and feel free to comment here or there as well!

Any comparison to the Apogee Groove?

Hi everybody, did someone finally test the Oppo-HA2 vs Celsus Sound Companion One ? Rockstar2005 of Stephen ? Or someone else ?
I am still hesitating between these two devices….
