Hey guys and gals, I have found much knowledge here on Head-Fi just by searching and reading. But now I think I need help. So a question from a long time lurker.
I have done a lot of reading on the Aune T1 over here and on Rock Grotto, a British forum. Since many people liked this dac/amp and because it is actually quite inexpensive, I decided to buy one to replace my NuForce uDAC. Mainly as an external amp/dac to use while watching movies on my iPad 1 (running IOS 5.1.1).
My main gripe with the uDAC is that it needs to be hooked up to a powered USB hub in order not to be rejected by the iPad because it uses too much power. This is how I connect it: iPad > CCK > USB cable permanently attached to a powered hub > Audioquest Cinnamon A to B out of the hub > dac > HP's. If I do not connect the CCK with the USB cable that is fixed to the hub, the iPad won't recognize the dac and plays music through its internal speakers.
Today I got my my Aune T1 in. It is beautifully made and looks really cool. Listening to it on V-Moda M-80's through a Macbook Pro while the tube is still burning in already tells me it sounds much nicer than the uDAC. My first impression is that the Aune, at least with the stock 6DJ8 6922 Russian tube, renders the M-80's character more natural. The bass is a bit less overdone now, while treble seems more extended and brighter. The headphones sound less dark now. Fresher! So far I am happy. The T1 feels much better than it is supposed to do for €160.
But much to my chagrin I get the same "the connected USB device requires too much power" message when I connect the Aune T1 with a USB cable directly to the camera kit on the iPad. iPad > CCK > Audioquest Cinnamon > Aune T1 USB > V-Moda's.
What am I missing? The Aune T1 is obviously self powered. I suppose it should draw no current from the iPad.
I had expected the iPad and the Aune T1 to immediately match. In fact, on many websites, the dac/amp is advertised as: Win7\Win8\XP\Mac\Ipad\Vista Support, just plug and play.
When I put a USB hub in between both devices everything works again. I was, however, hoping to get rid of that hub.
The whole problem is artificial anyway. When I disconnect the power cable from my hub, the iPad happily goes on sending music to the dac. So it is not a power issue per sé. It looks to me that it is more a protocol thing than that the iPad actually senses that power is drawn from it.
