I've never heard any hum with mine either.

I've decided to sell my black HA-1. If you are interest or know anyone that is, please let me know. I think it's a very price.

Hey Allan,
 
Sorry to hear this, what are you replacing it with?
 
Regards,
Paul

I got a great deal on a Sony UDA-1 (mostly for speakers) and I have BottleHead Crack (which I use with my HD800 as my primary rig), so I will use those for a while. I'm heading to RMAF in a few weeks, so I will check out the new gear and see if anything tickles my fancy. Possibly a Mimby/Jotunheim combo.

Sounds good. That's a nice price for a what appears to be a pristine HA-1. I'd almost buy it as a backup!

I have the UDA-1 as well and it's a good little unit with the conveniences of a remote and speaker amp.  I am only using it for speakers as well, which is rare.   The HA-1 is my workhorse right now.

Just ordered the HA1 and can't wait to try it with my Beyer T1.2 gen and Fidelio X2 headphones. It's been a crazy ride deciding and for awhile I was set on the iFi Pro Can amp but opted for the HA1 because it comes with a Sabre DAC and MFI iPhone input. Also like the ability to set the volume to a specific desired db level that I can see/gage as opposed to just turning the volume dial. Hoping to feed back results as soon as I have had time to digest how it sounds with my existing gear. Thanks

One of the things I love about my HA-1 is that there is absolutely no hum at all....really low noise floor with my Mac Mini and my HA-1 combo...dead quiet between tracks...

Keep in mind that the HA-1 volume knob is entirely analog - a high quality potentiometer. The digital dB level shown by the HA-1 is an approximation based on the knob position. A ladder stepped attenuator would be more transparent with perfect channel balance, but it's questionable whether the theoretical improvement would be measurable or audible.
 
This is not a dig on the HA-1 - I've had mine for just over a year and it's fantastic as a heaphone amp and as a preamp. It's clean, neutral, and transparent, reference level sound quality.

A lot of positivity for HA1 . I hope to be joining in soon

Just a heads up to anyone who isnt aware of this, but when I spoke with Oppo UK Support today, they have said the latest firmware is HA-1_1.4.3
 
After some shenanigans with this where they tried to send me a rar file directly via email (which gets blocked by spam filters), I was able to download this from their Amazon S3 website.
 
Cheers

Please link it, I don't think people would mind.

I tried to but I was told that because of my new member status it was referred to the moderators.

I'm very happy with mine. Wasn't a fan of the Oppo cans, but it doesn't matter: the amp superbly drives both my ADH-5000s and Nighthawks. In the case of the Fostex drivers, I never heard them as seductively beautiful before, not with Little Dot tubes, Peachtree's Nova, a Cayin tube amp or my trusty vintage Marantz receiver. Dead silent background; rich depth and presence, with DSD orchestral recordings sounding spectacularly emotional. To be sure this is also due to the DAC implementation in the Oppo and JRiver's OS X engine which get along very well.
 
Control via phone or iPad (with JRiver's app open too) makes lounging across the room with a glass of wine and the lights low almost obscenely blissful. There oughta be a law...to do this more often!
