Hey folks! I'm surprised this wallet-friendly device hasn't really been mentioned much here on head-fi. I recently stumbled upon a thread over at rockgrotto that basically raves about it, so I decided to order one from Aune on ebay. It just came in today. I'm listening to a FLAC rip of the new Pinback album as I type this, and I'm seriously shocked at how good this thing sounds. It sounds good, really good, like light-years-better-than-anything-else-I-have-ever-heard-no-contest good.I haven't done many reviews, and I literally just started listening to this device, so let me present you some brief points worth mentioning.
- I recently had the Audioquest Dragonfly in my possession and the Aune T1 absolutely obliterates it.
- Other sources I have experience with include the Sansa Clip+, IPhone 4, Sony S639f, S: Flo 2, Ibasso D1, and HRT Headstreamer
- The amps I've had have all been solid state--this is my first tube amp experience. Solid state amps that I've tried include Ibasso D1, Channel Islands Audio VHP-2, AMB Mini3, Digizoid ZO v1 (not really an amp but acts as one), and Audioquest Dragonfly
- What my experience means is that either 1) I'm blown away because I was born to listen to tube amps and didn't know it until now, 2) The Aune T1 is ridiculously good for the price, or 3) a mixture of both 1 and 2.
- The headphones that I use are a Symphones Magnum v4 build that I put together myself.
- It's also worth noting that the tube I selected to put in the Aune T1 is a Voskhod 6N23P "rocket logo" tube. I now use a NOS 6H23N-EB tube, which can be purchased here. It it's an awesome upgrade. Check back here later for some more in depth tube impressions.
That is pretty much all I have for now. I don't want to be one those annoying people that just raves about their gear simply because its new--I feel truly compelled to inform everyone here that the Aune T1 is in my opinion the REAL DEAL at only $200 shipped.
For those who don't like to read, here is my review in picture form:
********Here I will address some questions that seem to pop up frequently in this thread*************
Q: Where can I purchase the Aune T1?
A: I purchased mine from the official Aune vendor on ebay (auneaudio) but there are numerous vendors to choose from. I have not heard any negative reports yet from any particular vendor but YMMV.
Q: Does the Aune T1 come with a tube?
A: Yes, the Aune T1 does come with a 6N11 chinese tube.
Q:What is the "upgrade version" of the T1 that some ebay vendors seem to be selling?
A: The "upgrade version" on the T1 is identical to the regular version, but it comes with a better tube. My advice is to get the regular version, then invest your money in some good NOS (new old stock) tubes.
Q: What kind of tube works with the Aune T1?
A: Any tube in the 6dj8 family will work. This includes tubes marked 6dj8, 6922, 7308, e88cc, and CCa. If you are still not sure go ahead and ask in the thread or pm me and I'll let you know if the one you have/want will work.
Q: What tube should I buy for the Aune T1?
A: See the end of the FAQ for my personal tube impressions.
Q: Does the Aune T1 DAC utilize the tube, does the T1 headphone amp section use the tube, or do they both use the tube?
A: The Aune T1 is a USB tube DAC with a solid state headphone amp. What this means is that if you want the benefits of the tube, you must use the USB Input of the T1. The amp section of the T1 does not use the tube by itself. Technically, you could bypass the DAC of the T1 and just use the amp but this type of use is not really what the T1 is for. One thing you can do is use the T1 USB input then hook up a different amp to the RCA out of the T1. This will give you the benefits of the tube and allow you to try a different/more powerful amp (though I think the amp in the T1 is quite good). I personally have a speaker amp hooked up this way so I can use my headphones and some bookshelf speakers at the same time from one source.
Q:What headphones are adequately driven by the Aune T1 amp?
A: Almost every headphone I have tried with the T1 works very, very well.
Here is a list of headphones that I've used on the T1, and I think sound great:
Beyerdynamic DT880 and DT990 (250 ohm versions)
AKG K702 Anniversary
Symphones Magnum v4 and v5 (my favorite headphones)
I imagine that Grado headphones would make an excellent match with the T1 since the Magnums sound so good on it.
The Beyerdynamic T1 sounds good on the T1, but I personally found that it benefits a little in the bass department with the extra power from my speaker amp (I terminated the Beyers to banana plugs).
Headphones that needed more power than the T1 could offer:
If you change the cord or adapter then don`t forget to change it to one that has a FUSE in it!
IMPORTANT! - UK plug fuse should be changed to something between 0,5A - 3A fuse because in stock it comes with 13A fuse which is way too much!
Russian 6n23p Rocket logo
This tube is intimacy to the max. Warm, but not muddy. Forward sounding. Output volume seems higher than the other tubes I’ve tried. Very musical and engaging tube. It’s a fun listen for sure but it comes at the cost of some soundstage. Has a very punchy midbass but doesn’t have as much presence in the lowest bass notes. Has a kind of addictive tube sound.
Purchased here: http://www.boiaudioworks.com/6N23P
Very nice detailed sound, great soundstage and imaging. Less aggressive than the rocket logo. Has very, very good lower bass presence. Kind of a U shaped sound signature compared to the rocket logo. Overall, very good. Whether or not I prefer this or the rocket logo depends on my mood.
This tube ended up being a pretty big disappointment. Upscale Audio hyped it up majorly, but I found this tube to sound dark, very dark. Lacks resolution and just sounds a little “off.” I do not recommend it. Sounds like I’m listening to a cheap mp3 player instead of a piece of nice audio equipment.

RCA labeled Amperex 6dj8/E88cc
This tube is very nice. It’s kind of a middle ground between the two Russian tubes. It’s kind of laid-back in a way that is unlike those tubes, though. This tube is balanced sounding, maybe a little soft in the low end and a tad polite in the treble. It’s pretty natural sounding. Good soundstage and imaging. Overall a nice tube that maybe doesn’t have the addictive character that the rocket logo does and doesn’t have that ultra controlled low bass of the 6n23p-eb, but it does a lot right and sounds great overall.
Purchased from head-fi for sale forum.
Amperex 7308 Gold Pin
Alright guys, I finally got my hands on my Amperex 7308. This tube is the real deal no doubt about it. The first thing that stood out when I popped this tube in was man this thing sounds HOLOGRAPHIC. I've never heard anything have this much soundstage but still retain such smoothness. It's well balanced and dynamic with excellent details in the whole sound spectrum. Despite this, I decided to use the Rocket Logo 6n23p as my primary tube. The Rocket Logo has this addictive aggressive sound that I just can't shake. I believe that out of all of the tube I tried, the vast majority will prefer the Amperex 7308, but for me...Rocket Logo all the way...makes my Magnums rock so, so hard.
