I've found out who the original manufacturer is between maverick, grant fidelity, and XiangSheng . I went to Xiang Sheng's website and inquired about their dac-01 because on their website you can get options that's not available from the other two companies. Here's the excerpt from their website:
Note: DAC-01 Output Mode have the two following choose:
1, whether or not Volume potentiometer control line output:
A. Line output (connect with amplifier) and headphone amplification are both controlled by the volume potentiometer .
B. Only the headphone amplification is controlled by the volume potentiometer .
2. When inserting earphone,whether or not line output became mute .
A. When plugging in headphones, line output becomes mute automatically, only headphone amplification have output. When removing heaphones, line out recovers by itself.
B. When plugging in headphones, line output and headphone amplification both have output. You will need to turn off your amplifier to listen through headphones only.
Please specify your choose when ordering ( For example, reference format : 1A、2A ).If don't specify when ordering,we will ship item out according our default output pattern .
Our default output pattern is 1A, 2A.
1A means : Line output (connect with amplifier) and headphone amplification are both controlled by the volume potentiometer .
2A means : When plugging in headphones, line output becomes mute automatically, only headphone amplification have output. When removing heaphones, line out recovers by itself.
Finally, Please specify the Voltage you need , all Voltage are available.
I would love to have the preamp bypassed because the outputs would be going to my receiver and stax amp so I don't care for the outputs to be controlled by the volume. grant fidelity gives you this option for an additional 25.00. I also would love for the outputs to mute when ever headphones are plugged in. Grant fidelity doesn't give you this option(not that I'm aware of). So I contacted them about purchasing this and this is the response I got.
Very glad to hear from you and thank you for interesting in our products.

I was very surprise when I read this. Not only is the grant fidelity a rebranded DAC-01, it is a dac-01. But it appears that they are the only authorized dealer in north America, which is something FraGGleR stated earlier. But what we didn't know was who the oem was. I now will be ordering the dac-01 of ebay since it's now on sale for 187.00 shipped. Especially since the maverick dealer refuse to respond to any of my emails. I do like the look of the maverick better, but it's obviously a clone.
