I haven't tried T1 as DAC only but the amp is on the bright side.

I found it to be the amp. When I was running the Objective2 from the RCA outs, it wasn't as bright. I actually liked the HD600 + Aune T1 combo more than my other HPs. (All my other HPs were bright leaning).

some help for us potential  buyers..:)

 

Will it be ok to drive my HD555 (50ohms)..? ( I've read that headphone tube amplifiers are best with high impedance headphones )

 

I know that my HD555 will not benefit much by amp but i like the combo ,using also the aune as a dac ...(connected via usb to my logitech touch)

 

PS any other alternatives in the same price range,just to compare?

 

Thanks!

Yes, typically, tube amps are best with high impedance hps but. T1 isn't a tube amp. wink.gif Tube Dac + SS Amp so you're fine with the combo.

You're right!!:beerchug:

 

Any info on the headphone output impedance of T1?If i'm correct the lower the better (bigger damping factor)..

 

PS The only thing that stops me right now, is that i have couple of 12au7-ecc81-ecc82 type tubes (from a friend) and i just wondered if there is any similar to aune T1 compatible with 12au7 tubes..

post #2991 of 8012
The specs on it varies since there doesn't seem to be a "home" site but it says, 10ohm Here Also here

I don't think the tubes are compatible but I haven't ventured outside of the normal acceptable range in terms of tubes. Just stuck with the 6DJ8s mainly

In the official Aune site http://en.auneaudio.com/ they state the T1 headphone output impedance is 10 Ohm, as you can see here http://en.auneaudio.com/html/en_products/NewDesign/T-Series/154_20.html, Specification tab.

No, those tubes will not work with Aune T1. Just posted tube list 2 pages back:

Edit: LOL, I must be really lucky with tubes lately! Just won auction for 3x Miniwatt-Dario ECC189/6ES8 + 1x Mazda ECC189, only for 8.4€ (post included) ! ;D I already have 1 Miniwatt-Dario ECC189 and it`s very good overall performer with tightest&punchiest bass (but not flat&dry sounding) out of my collection. Impressions about this tube can be found earlier in this thread by search: http://www.head-fi.org/t/633006/aune-t1-usb-tube-dac-amp-discussion-thread-see-first-post-for-faq/2160#post_9546068. They are tinybit better than Miniwatt-Dario PCC189 or at least same. I`m really happy about these, hope they arrive safely! ;P Here`s seller pic:

Happy tube hunting! ;D

The tube was an Amperex 7308 PQ purchased a few weeks ago from a reputable seller measuring 12.5/12.0 & 12.5/12.0 mA/Gm (nominal new measure 12.0/11.5).

 

Anyone had a similar experience?

My second (and last) Amperex 7308 just died in the exact same manner. Not sure what to do now.

O_o

Thats weird. Try some other cheap tube and leave it on for longer time. If it dies too, then your T1 might have some problems. But it seems you are first to have such "tube-eating" problem.

I have burned my different tubes for a longer period a lot and no problems. And if those tube measurements are made by "eBay" seller then they may be totally inaccurate, never trust those measurements. 

post #2998 of 8012

I've put the stock Electro Harmonix 6922 back in but still too early to tell.

 

I also hope it's not the T1 breaking the tubes.

 

I came across good feedback on the eBay seller on numerous audio forums but yes it's still hard to tell whether they are honest.

post #2999 of 8012

How long usually a tube can stand and what factor that affect the lifetime? And anyone ever compare Aune T1 amp with Bravo V2 amp?

post #3000 of 8012

Hey guys, just yesterday i received my T1. I plugged the adapter into the socket and BOOM, some kind of shock happened. If my finger was just one inch closer to the socket i would've ended up in the hospital. I don't know what the hell caused this, but now the adapter is not working. Im pretty sure the unit itself is not defective, but apparently the adapter doesn't like our home's sockets. Anyone else have this problem? And how can i get this fixed?
