Aune T1 USB Tube DAC+ SS Amp Discussion Thread ***See first post for FAQ--Updated on 02/14/15***

Is there any difference between the Aune T1 with the 6n11 tube and the "upgraded version" featuring the 6922 tube (apart from obviously the tube itself) ?

There is no difference, and many of the "basic" T1s come with the 6922 anyway. Mine did. A good idea is to get the T1 without any so-called upgrades and buy tubes if necessary.

Oh ok, so it is safe for me to buy a "basic" Aune t1?
 
Also is buying from Pbuying.usa on ebay safe as it's the only place where I can get the best price?
 
Thanks for your patience.

That "basic" depend on the seller. Some will give 6N11 as stock. Some even claim "upgraded" with 6922 tube. As long the upgraded or the basic priced the same, I have no problem with that. And I think every T1 owner definitely will change the tube someday, unless the stock tube is perfect for them.

Considering purchasing this as my first tube amp/DAC. I want to pair it with the Beyerdynamic DT880 600ohms, thoughts on this? Will it drive them sufficiently?

I got mine in the us through Pennybuying. The service was fine. It took about 6 weeks to arrive from China. I don't know if it would be quicker to India. You may want to check CoiL's recent comments on some Indian tubes that he gave good reviews to. Good luck!

@Diabolique: Getting tubes here isn't easy unless I import them but teb1013's reply (brlow) has given me a faint glimmer of hope

Thanks a lot for clearing the pennybuying thing

woah! tubes exist in India :O
 
Need to check, are those comments in the last 10 pages?
 
The reason I ask is because I've started reading this thread from the first page and am about 30 pages into the thread

It'll drive them sufficiently in terms of volume but I don't know if you'll like the pairing with the 880s. I found it a little thin and bright due to the T1's amp.

Mine arrived today, I am planning on using the output to my Schiit Asgard 2, we'll see how nice they play together.

Just put India in the Search this thread function and you will find them. This is one. http://www.head-fi.org/t/633006/aune-t1-usb-tube-dac-amp-discussion-thread-see-first-post-for-faq/2925#post_9848413

I have a little over $150 to spend between an amp and a tube. I already have the T1 and an HD600 so would you guys recommend an O2 and an Ampere OG? I listen to mostly alt and prog rock with some indie and classical.

From what I can tell after taking apart the T1, the amp section is basically a CMOY with switchable gain.   For 600 ohm cans, it may make more sense to use the T1 as a DAC/buffer to feed an external amp.   I've been playing around with it feeding my Lyr and it is a significant improvement over the internal amp.

Go for Amperex OG 6Dj8/ECC88 (GAC coded is best for prog rock imo). Other options would be Ultron SQ PCC189/7ES8 (gold label Bharat India made, if you can find it, basically same sounding as OG but I find it tinybit better) or Siemens PCC189 (Mullard made) is also good for progressive metal/rock/djent. Also, there`s Siemens PCC88/7DJ8 (warmer tube than OG and for classical maybe too warm, littlebit smaller soundstage too if I remember correctly). Use search in this thread for more information and impressions, these are my main recommendations for progressive rock/metal/djent.

CmoyBB v2.03: 
 

1. Alps RK097 Volume Control and On/Off Switch
2. Bass Boost Toggle Switch
3. DC Auxiliary Power Jack
4. Automatic On/Off (senses headphone cord)
5. Texas Instruments OPA2227 Opamp in Gold-Plated DIP Socket
6. Texas Instruments TLE2426 Precision Virtual Ground (2x optional)
7. Decoupling Capacitors on All IC Supply Pins
8. Custom 2-Layer PCB: Compact Layout with Ground Plane 

 
Aune T1:

1. headamp board transistors are B649 / D669
2. Headamp board opamps are NE5532
3. PCM1793 DAC + TE7022
4. DAC opamp OPA2134

 
 
I know I have asked it already but has anyone tried or willing to try rolling opamps or maybe even h-amp transistors (for example like in case of indeed/bravo tube amp)?  Sorry if I told something wrong, I`m total noob about opamps ;D

Alright, I'll do more research on those. Since the search function also yielded a lot of complaints about the Aune amp, is there another one you would recommend at or slightly above $100? I was considering a little dot, but I don't want to spend money on tubes for that too. From what I understand the O2 is only slightly better than the Magni, and since they go for $120 on eBay they would be the best option.
