Nope definitely not too bright. The signature can change with a tube swap however, and I never use te stock tube. But still it never occurred to me that someone would consider it bright.

Thanks so much, I also e-mailed Aune. We'll see if i get a response. Feel free to PM me as well but I figured people would want to know about this issue if it is real.

 

By the way, I just plugged in my HRT Headstreamer II and it plays back fine at the full 24/96. I even switched devices in the middle of playback and no go.. the song just literally stops in its tracks. If I set the Aune T1 to 16 bit it continues fine though.

 

Hrmm m. It's not looking good..

Agree, although the Aune T1 is being presented as a tube DAC/amp it doesn't carry the typical warm sound that is associated with tube amps. It's a hybrid tube/SS amp. Where the pre amp stage is supported by the tube.   I certainly wouldn't call it overly bright at all. I experience the best of two different ways to use amplification presented through the Aune T1 and with a very respectable $200 price tag.

Ok, so I tried to set the mac midi settings to 24/96, and I definitely did not get playback either, so it's not your unit. I also tried 24/96 in Foobar for windows and it does seem to work. I'm not sure what you should do :(

Outputting directly to hardware, I have no problem playing the 24/96 track "Villain" by Lost In The Trees. Here's the output from my terminal:

 

$ cat /proc/asound/card1/stream0
GFEC ASSP DigiHug USB Audio at usb-0000:00:1a.7-4.3, full speed : USB Audio

Playback:
  Status: Running
    Interface = 3
    Altset = 2
    Packet Size = 582
    Momentary freq = 96000 Hz (0x60.0000)
  Interface 3
    Altset 1
    Format: S16_LE
    Channels: 2
    Endpoint: 3 OUT (ADAPTIVE)
    Rates: 8000, 16000, 32000, 44100, 48000, 96000
  Interface 3
    Altset 2
    Format: S24_3LE
    Channels: 2
    Endpoint: 3 OUT (ADAPTIVE)
    Rates: 8000, 16000, 32000, 44100, 48000, 96000

 

If I change to the 24/44.1 track "Dawn Chorus" by Beth Orton, Momentary freq automatically changes to 44100 Hz.

 

Seems like your setup is not able to change the sample rate correctly. I think it's a problem with configuration.

Well, I'm just unlucky I guess since my unit is suffering from the channel imbalance. Absolutely nowhere on the internet have I found anyone else with the same problem as me. Postage to China is too expensive for me that I might just send the unit for repairs locally.

 

They still sound kickass though.

As you can see, you are using LINUX, this is an OS X only issue, as far as I can tell. UNless you are incorrectly listing your OS. IF you can try this in OS X I am sure you will have the same issue.

 

HAS ANYONE successfully used 2/496 setting in OSX Mountain Lion? If so, please contact me, I am trying to fight with engineers who don't speak english and I am about just to give up and return it.

Stand by, as I am actively working on the issue now. I'll report in a few minutes what I come up with.

I just got it to work! here is what I had to do: 

 

I fired up Audirvana, set the T1 as the device and the gui shows that it is 24/96...I hit play and nothing happened...crap!

 

I did some reading, found out that some people corrected the 24/96 problem with other USB DACS by switching USB ports.

 

So, I switched USB ports and BAM it works fine.
