Well, yet, it is available if you keep it alive...so? Users still need to select what they want to output to if they are switching to multiple devices. At least for those that are using the HA-1 as a dedicated phone and pre for all of their use, it lets you power down and not lose the...

I've never seen this either, perhaps your unit is glitchy or reapply the firmware.

I am not sure what applications don't want to "switch away"...I don't even know what that means. All I know is Bit Perfect, Audirvana, Amarra, and Pure Music let you switch away even if the HA1 is powered.   Anyway, just make it an option   And the final idea was a simple tilt feature for...

When powering down the HA1 all softwares lose the reference to the ha1 in their output list. Re powering the ha1 does not cause these lists to refresh, so you must quick and relaunch the software, A keep alive features would keep the USB connection a love even when the amp is power down so one...

Oppo, any chance of adding a USB keep- alive option when unit is powered down, and perhaps a cross feed option?

Via balanced, I love this combination. I use Fab Filter Pro-Q 2 for minor tweaks to the curve with poorer recordings, but I would much rather have a phone/amp combination that reveals as much of the source as possible, as this is the only way to experience well recorded material.

I'm running a 15 foot active USB cable plus a 12 foot USB cable from my IMac 5k running Yosemite and no issue, silver Oppo HA-1

Imagine the inverse of this - all the good things you miss on great recordings playing through a "rose-colored" system...

This is precisely my feeling of the amp, as well as the Sennheiser HD800's via balanced. The most you can ask is that a rig faithfully reproduce the original material. Nothing is perfect, but I find my setup stunning in this regard. When you buy a DSLR, you don't look for one that softens the...

The HA-1 is neutral, not bright.

There is no ear fatigue...sorry you are pontificating for other reasons. It's a great amp and and DAC. We all have our opinions which is fine, but to denigrate to this level is silly. I bought the PM-1 and HA-1 together...the PM-1 went back because of comfort, and I would have had no qualms...

Did they indicte there was a newer firmware?

Oppo seems to be a very good company with excellent support, so hopefully they will take care of you.

Maybe a factory reset?: If you need to reset the HA-1 to its factory default settings, please hold down the Source Selector Knob on the front panel while at the same time press the MUTE button on the remote control. All custom settings will be erased and the factory default settings will be...

What troubleshooting have you done? Disconnect everything including power. Wait a minute, reconnect power,and try an analog source Can you try both the balanced and unbalanced connections? The is a circuit that reduce volume when balance is connected. Maybe that's got wonky and one of these...
