Hey, is anyone using the Oppo here to drive the Alpha Dogs, Alpha Dog Primes or the Sennheiser HD800?

I know it can drive them, but can it drive them well?

I know people have varying opinions on what constitutes good. I've never had a dedicated desktop amp (unless the Soundblaster X7 counts).

I want to know if a $400 desktop amp can drives the above-referenced headphones significantly better than the Oppo.

Just trying to figure out if the Oppo is going to hold me back as I start looking at higher-end headphones.

if it helps i have the oppo plus the hd600's which are rated at 300ohms.  the oppo paired nicely but i often found myself at max volume and wanting even a bit more headroom. so i got a desktop amp and ran the oppo to it via its line out and i can hear a noticeable difference with the additional power YMMV

My friend, Cornan, has found a fifth choice of right-angled cables for those looking to use an iDevice with the HA-2.
 
I've update the list, here:   http://www.head-fi.org/t/755879/oppo-ha-2-portable-headphone-amplifier-dac-discussion-thread/2775#post_12254347

Thank you so much.

Just to be clear, are we talking about Chord Mojo or something else? Because Chord Mojo is almost 3 times more expensive than HA2

Chord Mojo is $599 vs $299 for HA2 in the US.

Can you give me the link for the Mojo in the US?

On the gin would the Anker Astro E3 be a good buy to charge the ha-2 and iPod touch?

Thank you Zilch

 
There are other dealers here in the States, but I've done business with him and like his service.

I would think so, yes.  I've had the older, discontinued Anker Astro Pro 10,000 mAh battery pack for almost two years and it's still going strong - no problems.  
 
The Anker Astro E3 looks a lot thinner, but with the same capacity rating, for a lot less money.  The prices keep going down on these.  Snap it up!

I was just about to post a recommendation for this product:  
 
 
Drok Dual USB 2.0 Digital Multimeter 
 

http://www.amazon.com/DROK-Multimeter-Capacity-Charging-Alignment/dp/B00J3JSEG6
 
Here it is, plugged into the HA-2's USB charger, simultaneously charging the HA-2 and an iPod Touch 6, while providing a constant readout of the voltage coming from the charger and, best of all, how many amps are being pulled by the two devices:
 

 
When the amperage falls to 0.00, they are both fully charged, but I'm able to unplug first one, then the other, to get a feeling for how close either of them are to a full charge (without having to judge by turning on the iPod to see its battery state indicator or look at the four LEDs of the HA-2.
 
I've also been using the Drok with the HA-2 charger, for several months now, for simultaneously charging my Sony Walkman NWZ-A17 and the HA-2. I've not encountered any problems whatsoever and I like being able to assess the progress with a quick glance.

Is there a comparison anywhere between the Oppo HA-2 and the Pico Slim? I have the Pico slim (bought for my beloved custom IEMs that have been tragically left on an airplane somewhere...). I just bought the PM-3 and am considering the HA-2. Pico Slim should be able to drive these headphones, right? They have a low impedance, similar to some IEMs.

To be honest I can't discern a huge difference when I play Tidal HIFI through the amp and when I play through the phone direct...

But these are my first ever over-ear headphones...

Anyone been able to make a direct comparison Pico Slim vs HA-2?

Thanks and hello - this is my first post.

Hi
Just obtained this wonderful piece of equipment but i have an issue with the otg cable. Anyone knows any right angled otg cable for android? And care to share how you guys manage the cables? Like in a pouch?

Thanks

For users of this unit with Apple lightning equipment, I am wondering what you experiences have been?
 
I use a lightning CCK to output my phone to various external DAC units, and the experience is mixed at best.  I get dropouts all the time, and these dropouts require going back to the phone and hitting play again.   Sometimes I get white noise, etc.
 
So I am wondering if this unit is more reliable with iphones than with using the CCK.
 
My iphone is a 6 plus, running 9.2
 
Thanks.

I've had the HA-2 for a week and did not have any drop outs with my iOS 9.2 devices (iPhone 6S, ipad Air 2).

Only issue: when the device sleeps for a while without playing audio, I sometimes have to reconnect. But never during play.
