Hey Folks, I'm kinda new to this forum. Gained lot of knowledge by following this for few days. I just got my brand new Beyerdynamics T1 Tesla headphones. After following this Aune T1 thread, got interested in that and ordered a silver Aune T1 with EH 6922 tube. I even ordered a Telefunken E88CC tube as it got some rave reviews. Is this setup really going to fire up my Beyers with ease as it has 600 Ohms? How much headroom I can expect? My source is going to be a Macbook Pro and all my collection is in either 24 bit 96khz or 24 bit 192khz and most of them are from HDTracks. Do I really can make out the difference between the tubes? Advance thanks to all the forum members

Wow a Beyer T1. Not sure about it but I think it will benefit better from something more powerful.

Op has a really small blurb on the beyer t1 running of the t1. says that the bass benefits more from something with more power( voltage) like a otl tube amp or speaker amp

In that case, may be in the future I should go with Woo Audio WA7

I was just looking around ebay to find a good deal on this Aune T1, when I stumbled across HifiMeDiy Sabre USB DAC and though it was some kind of a mistake, because this device cost just around 30£, where as the Aune T1 costs around 130£. I checked the components and they were very similar, sure the HifiMeDiy lacks the extra analog inputs and outputs, and the tube amp, but its so small. I then had a read of some HeadFi posts to find-out if the sound quality of this device was good, and the reviews confirm this.
 
I look at this small HifiMeDiy PCB and then I look at the Aune T1, which is much bigger and seems to have more components, and I don't understand how can you achieve the same audio quality with what appears to be much less components and a smaller price tag?

Dude you pretty much answered your own question. T1 is a tube DAC with solid state amp. If you break the T1 into smaller components you notice that it has power cord, transformer, detachable USB cable, solid state amp, volume control, stock tube... Amps get warm so it's good to have some empty space inside the unit. If you only need DAC and don't care about tube rolling + those extra components, then HMD seems like a nice deal. There are so many options for different budgets and needs.
 
In addition, this is not the only small DAC out there or even the smallest. uDAC is also relatively small and then there are those USB stick DACs. DragonFly products, for example, can have DAC / preamp / headphone amp in a single USB stick. They use this same Sabre chip technology, which enables very small size. I personally like it when my headphone amp/DAC has some physical size and nicely glowing tubes
 
One thing is for sure... If you are looking for a DAC only, Sabre ES9023 chip for 30£ seems like a awesome deal! T1 has BurrBrown PCM1793 conversion chip, but I don't know how it compares to the Sabre.

Text position and getter suggests 60's Mullard (more likely IEC than shield logo). This being said I actually think it's Mullard, Blackburn made GE tube (maybe from 1969): http://www.ebay.com/itm/A-Pair-of-Mullard-Gold-Pin-6922-Tubes-/370696978125

E: I'm sure it's very nice tube!
E2: Just noticed the GE tube to have a large halo getter...

Thanks Salvatore!

I enjoyed reading the links to tubeworld as well and reading more about the tube descriptions.  It certainly fits the description on that site in terms of sound.  I was just curious since so far it's my favorite tube and would like to have a backup or maybe step up to higher Mullards someday.

thanks! now I kinda regret not getting this amp. Have you tried the O2 amps? if so how does it compare?

 
I can't say I've experience with the O2 amps.  However I was looking into getting either the Schiit Magni/Modi stack or the O2 before stumbling on this thread and eventually deciding on the T1. Instead. 

Based on what I read before here http://www.head-fi.org/t/642401/comparison-and-review-magni-modi-vs-o2-odac it seems like more or less the Schiit stack and the O2/ODAC are even. The Schiit stack winning out because it's of better value.  But I've listened to the magni/modi and I honestly feel the DAC and amp section on the T1 is much better and comparable to higher amps.
 
Plus you get to have added fun with tube rolling

How much Voltage output can we expect from Aune T1 when connected with Beyerdynamics T1 600 Ohms headphone. Are anybody facing issues with the Aune T1 when connected with higher impedance headphones?

Yes I know that I pointed-out the difference between the two, but what I am trying to say is that it seems as though the HMD has all the expensive components in it, which are just as good as those in the Aune T1. It has a decent DAC, the USB controller is the exact same, after that it just leaves the AMPS (which I can't find, same or not?), the tube itself (extra 20$?), the other electronic components and ports aren't the expensive parts. The body looks nice, costs another 20$? Therefore I am not sure if that 100 difference is justifiable, I mean only in terms of audio, of-course in terms of appeal and connectivity the Aune T1 is better.
 
Also would be be possible to use the HMD as a DAC, so that I can plug it into another AMP, and only then connect it to the headphones? (double amplification good or bad?)

I've ran dt880/600 ohms from the Aune T1 before, it works just fine but I didn't find them to pair well. I don't think the Beyer T1 would as well since Beyer T1 is bright like the 880s and the amp on the Aune T1 is bright too.

HMD is just a dac, no amp portion. The 3.5mm jack is a line out for other amps.

Ok guys, I have two headphones options with the T1 and am asking for your thoughts. Currently, I have an unopened DT 880 Pro with me however, I could get the 600 Ohm Premiums for an addition $40. Is the T1 able to sufficiently power the 600 Ohms or should I stick with the Pros? Personally, I like the aesthetics, the looser clamp, and the straight cable of the Premiums more to justify the $40 but if they sound worse then it may not be worth it.

Yes, but I am 100% set on the T1 as well as the DT 880; just deciding if I should keep the Pros, or get the Premiums. You said that they don't pair well but does that mean they sound worse than the Pros with this DAC/Amp?

The difference in ohms between the 880s are very minor. And the difference between the pros and prems are cosmetic thus the 250 pro and 600 prem should sound pretty much the same. Graphs show the 600 ohms being smoother treble wise. The above comment wasn't meant to discourage you, it was just meant to let you know that they power the DT880/600s just fine, just doesn't synergize well. They don't pair well because it's a bright headphone with a bright amp so it exacerbates sibilant recordings so if you're sensitive to treble, you wouldn't like the outcome. But with that said, you can always use the lineout and connect a warmer amp to the T1, which I have done myself.
